[Q] Setting up XOOM on WiFi without PC (deploying) - Xoom General

I am deploying to Iraq very shortly, and for a pretty decent length of time. I plan only taking my XOOM, decided against a laptop. My understanding is that there will be internet service where I am heading, so I plan on getting it installed in my little hooch. I will also bring a router to setup a wifi connection, and herein lies my questions:
1. How do you setup a router if you don't have a PC? I might be able to borrow a friend's laptop to set it up, is that my only choice.
2. Is there a recommended router for the Xoom that works better than others?
I'm not a newbie when it comes to computers/technology, but this will be my first deployment without a laptop. Appreciate any help y'all can provide.

You dont need a PC to set up a router. You dont even need the internet to use a router. Just connect to it with your xoom as if you had internet.
You just need to find the default gateway address to enter into the xoom's browser when you are connected to it. There you can setup whatever you need.

@OP
Why do you need a router? Are you limited to only one connection that you have to share among several devices?
As said, all routers have a web interface that's accessed via its IP address. Depending on the brand, it's usually 192.168.x.1. You do need to have a device (not necessarily a PC) with a wired RJ-45 Ethernet connection to config the router. It's possible to config it via wireless, but there's a good chance of getting locked out if you mess up. It's not recommended.
If you are a tech newbie, configging routers should not be on your to-do list, as networking can be a can of worms. If you don't have to have one, then don't.
If you do buy one, stick with the well-known brands like Linksys/Cisco, Netgear, D-Link, etc. Vendors typically have a newbie-friendly line that's supposedly easier to set up, although I can't speak with firsthand experience. For example, Cisco has the Valet line easy setup, and the E-series for tech users.

He will need one to set up a wireless network so his Xoom can use the internet.

For what you're doing any of the basic models would work. The configuring that you will have to use the IP address interface for would basically be setting a password (recommended) and troubleshooting if you find yourself without internet connection.

WiFi client detection software?

Hi, thanks in advance for help.
I have someone leeching off my Wifi net, who seems to be able to 'break-in' no matter how i secure the WiFi net.
Anyone know of any free Windows Mobile software that will show signal strength of Wifi CLIENTS nearby. Not Access Points, but CLIENTs.
I want to go find this guy.
thanks
Hi there!
If you got an "leecher" on your network I would recommend you to start your search on your router.
You didn't provide any specs, how did you find out that someone is on your network?
Next question, have you changed both, router pass and wlan key?
Are u using weak encryption (wep)?
Whats about your mac-filter?active?
I would guess you've got an dhcp server on your network/router... go there and check the dhcp releases. Any suspicious entrys? You should know all the devices listed there. If you have found a IP you don't know, ping it and check if its alive (those packages can be ignored by the host), try to access it via smb, you could also try a demo of languard and try to read out details like os, user, owner...
I'm almost shure you can't use your wm device to locate a client of a network, unless you can switch your wlancard to ap-mode and he connects to you ^^
Nope, need signal strenght reader if poss.
Thanks for the comment, but I'm pretty security savvy, and have done most of what you recommend.
I actually can't believe he's still getting in when I've locked down so tight.
Anyway, it's a CLIENT signal strengh program that I'm trying to find.
Rogue clients are malicious wireless client devices that either try to gain illegitimate access to your WLAN or try to disrupt normal wireless service by launching attacks. There are numerous ready-to-launch wireless attack tools freely available on the net. Many of them are open sourced and work pretty well with most Wireless client cards. This turns any curious mind to professional hacker in minutes. Many do it simply for the pleasure of being able to disturb someone remotely. All these developments force WLAN administrators to give a second look at any wireless client that is misbehaving.
What means most of that what i recommended?
Did you actually change the router password AND the wlan key?
Sorry, I don't think that you can trace him with your mobile. as long as hes not connected to your mobilephones wireless network (wich requires your mobile wlan device to switch to ap-mode).
Forget about that.
Please tell us, why do you think somebody is on your network, how did you find out... whats the "evidence" for you that there is somebody.
I'd like to help u, but i need some further details to lock him out.
I hope you know that its just a matter of minutes to break a wep key. GPUs are used to decode it, which is damn fast!
So please provide more specs about your network.
Greetings
1: Use WPA instead of WEP.
WEP is crackable in a matter of seconds.
2: Assign access control/MAC filtering
3: Use your network in ad-hoc mode
Well, WPA is crackable too.
The person in question might change his MAC to yours and create collisions anyways
Can you be sure that he has really associated with your router. I have noticed some client/router combinations "apparently" associate but all traffic is blocked because they did not provide the right key.
As others say - use WPA WPA2 and use a strong (non dictionary) passphrase
get a computer that can run airodump or something similar.
run airodump with it set to the channel of you router - not in hopping mode as you will miss lots of packets.
Airodump will tell you the strength of the signal from his computer so if you have this on a laptop you can move around and possibly can an idea roughly where he is
Thank you, i will try Airodump
Thanks in particular Scote.
I didn't list the router config simply becuase I am confident it's pretty secure:
Router is a new Belkin N1
- 63 random char password from grc.com/passwords
- SSID is "netgear" even though its a Belkin : intention to mislead for access URL.
- WPA2-PSK AES encryption
- SSID not broadcasting
I didn't bother with MAC filtering, as I understand a good 'hacker' can spoof it : If this guy can get through WPA2 I would say he can probably MAC spoof.
My 'evidence', is that up to 3 unkown computers turn up on the 'Clients List', around 4 hours after I change the SSID/password : Each time.
I have 2 laptops, so I will try Airodump or maybe Backtrack (suggested elswhere) on these as a 'direction finder' based on signal strength.
Hmmm...I did read somewhere you can set a Kaiser to be an access point...
Thanks all
Yes you can.
Someone found his stolen Wii/mobile phone (don't remember which one) that way.
There was even an article on the net.

bridging two subnets?

ok, i have two routers
Asus rt-n16, which is my primary router, and is connected to the internet, running tomato usb, 192.168.1.1
Dir 601, which is running dd-wrt, client mode, subnet 192.168.2.1
[long story: i actually have 4 routers, those two and a wrt54g v6 running dd-wrt, and wrtu54g running stock. my goal was to run the Dir 601 WDS mode, to extend the range of the rt-n16. sadly, the two routers do not seem to agree with each other hardware wise, so i coudn't do what i set out two do. so i basically re-shuffle my routers which leads me to the problem i have now]
so basically, i need a router to plugin my directv box (hr20) and a bluray player. it seems the only way i can get the Dir601 to do this is by using client mode in dd-wrt (client-bridge doesn't seem to work for some reason). client mode means a separate subnet.
the hr20 has some media-sharing functionality which allows it to stream some media files shared in my network. especially nice since rt-n16 has NAS functionality.
however, my entire network lives in 192.168.1.* and the hr20 is in a different subnet connected to the dir601.
my first question is: has anyone had any experience with rt-n16 and dir-601? one is atheros and the other is broadcom, dunno which is which, but apparently, they don't like talking to each other, especially in a bridge-type relationship. is there a way i can set these guys up such they they are in the same subnet?
my second question [assuming the first question is not doable]: what can i do to bridge these two subnets? i don't really need to bridge them per say, i just need all computers in the network to detected each other for the purposes of media sharing. [ port forwarding of sort? ]
i have enough experience with dd-wrt/tomato to tinker with it, but sadly, little knowledge of networking. if anyone can point me to the right direction, i would greatly appreciate it.

I have two routers connected more or less in the way you described, except by ethernet cable. ROUTER1 has modem for internet. ROUTER2 has ROUTER1 plugged is as WAN modem.
internetz--------ROUTER1(10.0.0.1)-----[ethernet cable]----(10.0.0.2)ROUTER2(192.168.1.1)------WIFI-CLIENTS(192.168.1.x)
I can easily ping 10.0.0.1 from any wifi client. I can also ping 10.0.0.2 and 192.168.1.1.
So here are your two subnets. It just works in my experience.
P.S.: I'm afraid I must say WDS isn't standarized enough to be used if you have two different chipsets.

Reverse Tether

My University does not allow Wi-Fi in the dorms because they say it "puts a strain on the network". This includes Mifi's and mobile hotspots.
I have OS X Lion and Windows 8 (Dev Preview) through BootCamp and I get internet through ethernet. I need some way to share internet access from my MacBook Pro to my A500. I also have a rooted Samsung Fascinate, but I cannot Tether at all with it because a. I dont have enough data a month to do that, nor do I have the money and b. the root apps give errors no matter what rom I run.
Buy a wireless router and passcode it.

If your major has anything to do with IT look into another school.
At least if they are not providing their own wireless network and that is the only reason they don't want you to have one.. otherwise the reason you provided is fud if you had a personal nated + wpa 2 protected + hidden network..
Otherwise:
The A500 cannot reverse tether without root. With root you can sorta do it via a root shell and linux commands.. You end up with a connection but many apps think there is none, fine for me surfing the web on the bus but you can't use market and apps wont auto sync.
Some custom firmwares based off the Asus and other android tablets with the same chip set do have true working Bluetooth tether. Thus may fill your needs better.
(Actually I see partial support for Bluetooth tether built into the 3.2 update, but forcing it enabled made the tablet crash, and still needed root to force the option to exist)

Nah, may also need to disable your essid and clone your desktops Mac address.. otherwise it may disable the Ethernet Jack.
All wireless routers ive seen can do this out of box.. even if I like updating them with openwrt firmware.
can your Mac provide an adhock network?
When my friends router shat itself all he had was a adsl modem with eather net out. He set up his I Mac's wifi so that his iPhone could connect to it (over wifi) in the house. He had lously cell connection where he lived.
Can you do some thing like that and get your tab to connect to your comp? Or am I not understanding the problem?
Good luck.
OP,
Well you are kind of screwed - soft of.
It is the schools network. They can dictate what they want on "their" network. And even if you hid it, etc they still can see what it plugged in.
But they can't tell you that you can't have WIFI at all. WIFI runs on 2.4 Ghz for B/G/N and 5.0 Ghz for A/N bands that is unlicensed frequencies. So if you have a some other Internet connection, ie 3rd party like DSL, Road Runner, whatever, they can't tell you that you can't use WIFI. They can only control their network.
The reason I mention this is because I have seen WIFI Nazi's out there trying to be all macho even when it isn't their network. You might be fortunate enough to have WIFI in the area that you can use, say a friends close by that has commercial ISP and wireless. Also possible to use DD-WRT to put a router in client mode to pick up a signal farther out and and a 2nd router to broadcast that signal in your room.

[Q] Anyway to share my N7 wifi with PC?

So, at my college there are two networks that a student can use, one designed for computers (that has a proxy) and one that is designed for mobile devices (no proxy, requires MAC to get on.) I was wondering if it was possible to share my Nexus 7 *WIFI* connection to my PC...

Your pc got a wireless dongle?
If so just turn your Nexus into a Hotspot, connected to the Network you want
Then connect your PC to your Nexus ??
Well, I didn't make it clear. I have a wifi version N7. All I want to do is share the wireless connection that the n7 is already on with my PC. So a wireless tether would not work.
You can try to spoof your N7's mac on your pc using Mac Makeup. Your pc needs a wireless adapter and spoofs your n7's mac, so it should connect to the mobile wireless network. You probably won't be able to have both devices on the wap concurrently.
I'm guessing the reason you're looking to doing this to bypass the proxy restriction your school placed on the resource. Keep that in mind in case you decide to download a ton of torrents and they trace the usage back to your N7's mac.

Yes, they would, but so what? Are they going to check all Asus devices? I'm sure there's plenty (unless you're in US, then Asus is very outstanding among all macbooks and iDevices). And you can't just assume he's going to download millions of illegal stuff. Maybe he wants to download Ubuntu via torrent
OP: I have not seen such a thing, there's normal tethering (3G to wifi hotspot), 3G-BT, 3G-USB, but I have never seen wifi-usb.
http://forum.xda-developers.com/showthread.php?t=1792245 check out this thread. With this adapter, BusyBox and some (more or less) basic knowlege of linux networking, I'm sure you could successfully share your wifi connection trough LAN cable, but I doubt it will ever work trough USB.
If you're running linux on your PC, then faking MAC address is so simple, that it's a better shot, if you're running windows, it's a bit trickier (but still doable).
Faking the MAC on a PC is simple too.
I'm not sure I'm even following this thread. Spoof your PC's MAC and jump on the mobile network. Done.
ALL devices have a MAC... so if they REQUIRE a specific MAC for access then they can trace everything you do online back to you. In that case I would be very cautious on what you do. They can also monitor bandwidth to your MAC (PC) and see you are pulling WAY to much bandwidth for a mobile device. If they don't care, then whatever but you may be getting a knock on your door.
You are basically circumventing their security policies and could put you in some trouble. So Clone your MAC address and keep it simple.
I've seen WiFi hotspot. Not sure if it was baked into sense though

Internet issues with Android devices at school

Hi,
Just got a shiny new Galaxy Note 10.1 last weekend. Yesterday, after receiving my case and keyboard from Amazon, I brought it in to school to start taking advantage of the S-Pen for note taking in classes that keyboards don't quite cut it in. Unfortunately, it revived an issue that I had and ignored on my HTC Rezound from last year... an issue that a WiFi device can't ignore, and unfortunately my phone's battery is not up to using CM10's tether function all day (and it might start running down my monthly data being used 5 days a week, all day).
So, any ideas what might cause this issue? The school primarily has Macs, and my Windows 8 Laptop sometimes has issues, but at least half the time it works fine. It is just Android devices that will not work. They connect, and get great signal strength, but just won't get any actual data. To my knowledge, nobody has ever gotten an Android device to connect. My Rezound is running an unofficial CM10 (4.1 JB) version, and my Note is using whatever the newest official update is (4.1 as well, I believe. Non-rooted). I don't know a whole lot about this type of stuff, but I'm not afraid to tinker around to try and get it working. I've tried a few other suggestions from numerous Google searches, but to no avail so far. The network is unprotected, and run by the school's IT people, so needless to say I have no way to easily change settings for the campus' network. I'd prefer not root the Note just yet, but if I need to, so be it. Any ideas what this might be?
Thanks

Some more info:
I cannot ping the tablet from my laptop (I get no packet loss, but all return 'Destination Host Unreachable'.
Same result if I try pinging my laptop or the router from my tablet using Terminal Emulator.
Sometimes, if set to DHCP, the tablet will give an 'Authentication Error Occured' error (or similar, I don't recall the actual wording). Sometimes it indicates a connection, but just won't work. I've never had a problem connecting using the same info as my laptop (with the IP changed, of course), but again, no internet, no ping.
Thanks
May or may not be the problem, but from what I've noticed, school networks tend to have a lot of blocked ports. I know the main Google Sync Framework uses port 5228. Try shooting an email to a network admin in your school's IT dept, asking about that port or just in general if they're aware that Android devices are unable to connect on their network.

What do you mean by "same info as my laptop" what types of credentials are you referring to? Something you have to change on the laptop in order to get in? The more information regarding this you can provide (safely, mind you, mask/alter any sensitive info), the better we can assist you. If you have to do something like set a VLAN, then you're never going to get an Android device to work as we do not have the capability to use VLAN'd wireless like most PCs and Macs can with the proper configuration changes. If there's some browser catch-all page, then that should work, but based on your statement "with the IP changed" leads me to believe that you're messing with the adapter settings directly. I would be especially keen to helping you with more detailed networking issues like this should you provide me with the information requested. I look forward to your reply. (Yes, I like technical challenges like this, it's why I work VoIP support.)

since you know ping, then did you check the IP address for each device?
Back to basic:
1: ping your device gateway IP
2) if ok, then ping ur device (tablet or laptop)
3) if ok then ping bbc.co.uk (this will check your dns), if failed ping your dns's IP address.
If no IP on android, then check if there is any protection on device. It sound like no IP been allocated for you.
Depends on how good a school's IT dept. I have not seen many school actually put filter to stop non-window device.
I am not sure it has anything to do with VLAN yet. As a simple logon, device does not care VLAN or no VLAN.
The basic for us is 1) get an IP on device. 2) know how to get out (gateway IP) 3) interrept hwere you go (DNS resolution) 4) know how to get to internet (internet router, internet firewall, internet boardband et...)
If you have authentication error, then it is sure you are not going to get an IP address. If this is WiFi then check on security (WEP, WAP...TKIP...)

Hello Coffeeist,
Please contact your schools IT department and find out what kind of encryption they use on their APs.
If they use TKIP, then that is whats causing the problem with android devices.
Once TKIP is disabled on the AP you are connecting to, you will be able to reach the internet.
I say this because I had the same problem in the past (setting up Cisco APs), and can confirm that this is the cause of the problem.
TKIP shouldn't be used anyway. They should be using AES. TKIP is too weak.
I guess that last part answered another question that you might of had. (Why TKIP doesn't work with Android?) Android=Secure TKIP=WEAK.... Unacceptable for Android
Also, you mention something about not being able to ping your tablet from your laptop. If I understand this correctly, you have both your laptop and tablet connected to the same AP and you are trying to ping between the two. This wont work in most cases. Reason: "Port-Protection", which if enabled doesn't allow clients on the AP to communicate with each other.
Regards,
Ed
Let us know how it goes.

Just IP/DHCP/DNS (and I've also tried public DNS such as Google). Nothing fancy set up on the laptop (everything should be on Windows default network settings, same with Android on both devices). There is also no catch-all page, assuming I'm interpreting that correctly (as a login page sort of thing, like I'd get at Starbucks or a Hotel).
Glad to provide the challenge... truth be told, underneath the annoyance of lacking connection, I love issues like this because of the fun tricks and such that solving them can teach.

1. If I recall, this either had full loss, or Destination Host Unreachable, when pinging the gateway IP from the tablet.
2. Have tried this nonetheless, and I think I made it through once or twice just after turning on the tablet, but after that would only get Dest. Host Unreachable.
3. Had tried with Google, fails across any DNS.
I seem to get an IP, although sometimes I get the authentication error in Android and it won't connect. Whenever I set a static IP, based off of my laptop's IP (not the same, of course), I get connected, just no internet.

Unless I am totally clueless about this stuff (er, moreso than I though I already was), it uses neither TKIP or AES, being an open and unsecured network.

Haha, I doubt it. None of my friends, especially the ones who I think would even try and do something like this, are tech-savvy enough for me to have any suspicion of that. Thanks though
Another piece of info (a pretty weird seeming one at that): Sometimes, I'll turn on my tablet in the middle of the day, and out of the blue there is an email notification there, for recent emails. Of course, if I go into browser, I can't get any pages. Can't think of any other networks that the device could/would connect to on campus, either.
Thanks!

First off, thanks for all of the posts, and I apologize for taking so long to respond.
Also, I did check port 5228 with my laptop, and it seemed to indeed be closed. Haven't been able to contact IT yet, but I will need to soon to solve an issue with another, unrelated issue.
Just IP/DHCP/DNS (and I've also tried public DNS such as Google). Nothing fancy set up on the laptop (everything should be on Windows default network settings, same with Android on both devices). There is also no catch-all page, assuming I'm interpreting that correctly (as a login page sort of thing, like I'd get at Starbucks or a Hotel).
Glad to provide the challenge... truth be told, underneath the annoyance of lacking connection, I love issues like this because of the fun tricks and such that solving them can teach.
1. If I recall, this either had full loss, or Destination Host Unreachable, when pinging the gateway IP from the tablet.
2. Have tried this nonetheless, and I think I made it through once or twice just after turning on the tablet, but after that would only get Dest. Host Unreachable.
3. Had tried with Google, fails across any DNS.
I seem to get an IP, although sometimes I get the authentication error in Android and it won't connect. Whenever I set a static IP, based off of my laptop's IP (not the same, of course), I get connected, just no internet.
Unless I am totally clueless about this stuff (er, moreso than I though I already was), it uses neither TKIP or AES, being an open and unsecured network.

Based on your responses, I have a follow up question and comment. The question is as follows: Did you have to register your computer with your IT when you started school in order to be permitted on the wireless network? If this was the case they're likely filtering based on MAC address (which you won't be able to spoof on your Android, but you may be able to spoof on your laptop), get them to re-register your laptop after you spoof the MAC address so you can get both devices on using the same MAC address (though not at the same time of course unless you're fine with stuff randomly not working). The comment is as follows: Yeah, finding the workarounds to get back limitations like this is definitely a fun challenge because when you win, you've definitely learned something new. Oh, and you were right about my question of the gateway authentication page like a hotel wifi login page.

Nope, it was up and running just through connecting normally, and has been since (mostly) - no registration or anything like that. Now, the reason that I put 'mostly' in parentheses is that sometimes the computer will be connected, but also have no internet (I don't think this started until I, dare I admit, upgraded to Windows 8). However, this only happens sometimes, whereas the Android devices never get internet access.
However, on the topic of MAC addresses, one post (in fact, I think it was on XDA) I saw awhile back while Google searching this problem was that someone had a similar issue, found to be with their device's MAC address having the letters 'FA' instead of 'FB' or something like that. Being that my Note isn't rooted, I haven't tested it with that, but perhaps I should give that a try with my CM10 Rezound?

That shouldn't be it unless they have corporate level routers that don't recognize the MAC address of any devices manufactured after 2009 (when most of these manufacturers got the MAC addresses assigned to them (this is VERY unlikely)). I would honestly work with IT on campus and advise that it appears not a single Android device is allowed on the network. If they're blocking Android for any reason, check the terms of service for using the WiFi and see if there's any provisions for banning an entire brand of device/OS for whatever reason. If there's only provisions for individual banning, then take it back to them and show them that your record has not been abusive in the least and go from there. Make a case, otherwise draw one up with legal council. *shrugs* I don't believe anyone should ever be punished for the type of device they chose to purchase, that's first amendment choice, but it really comes down to their terms of service which you agree to by using the wifi.

Sorry to bump the thread, but seeing as it's my own I figured it would be alright...
I got around to asking the the school IT about the issue, and they said that the deliberately block mobile traffic, which they went on to find out does include Android tablets (I understand phones, but I can't even begin to understand why they target Android tablets... unfortunately, that's not my call). I Google searched a bit, and found that networking devices from a company called Aruba can be set to block traffic from specific types of devices (supposedly Cisco and a few other companies can do similar things too), by checking something with the HTML version, or something like that (I'm by no means a networking expert hehe).
So, I guess I'll make my last effort with this thing, and ask if anyone knows of some legal, non-hacky way of getting by this?
I'm guessing not, but worth asking.
Thanks

Before discussing any workarounds, you may need to review the Terms of Service for your wifi on the school premises first, review the consequences for bypassing their security measures, and figure if it's worth the risk to you... At this time, it'll be kind of "hacky" to get around such a block. In order to provide you with a valid workaround though we'll need a little bit of information regarding what's going on when you connect.
First, when you connect to the WiFi with your Android device, do you even receive an IP address? If you don't then we'll stop here, the only way to get around the types of blocks they're employing at this level would require hardware hacking/firmware reprogramming to change the identity of the device itself, which is flat out illegal in just about anywhere I can think of. Here's your checklist, fill out where applicable: (Even if you set static information to accomplish this, that will be a valid Y.)
Get an IP? (If Y, proceed)
Is it a valid IP address on the same network as your PC? (Either way, don't care)
Can you ping the gateway you got from DHCP on Android? (If Y, proceed)
Can you ping the DNS server(s) you got from DHCP on Android? (If Y, proceed)
Can you ping an external server such as Google DNS (8.8.8.8) on Android? (If Y, then we're done here)
It's kind of a bit of a process unfortunately, however, if you pass every single one of these tests with the Android device, there's good news. They're only filtering traffic based on the User-Agent identification of all your applications (and based on the MAC address of your device, denying your DHCP requests), you should be able to bypass this with a VPN tunnel back to your home from your Android (after setting your static IP) in order to encrypt and keep this information from leaking to their systems. However, this will likely set off alarms if they monitor their network heavily. If the school IT asks, then you're "working on projects in-between classes on your computer at home and your family has a home office with VPN already, so you used that to connect back to the house". Either way, they can't say much about it besides cut you off... again. Anywhos, I wouldn't recommend trying to bypass without doing all this research first, and then also evaluating the possible consequences, however the rewards are within themselves. You'll be the only person at school with a working mobile device, (besides those iSuckers). Technically, encrypting your traffic is completely legal (and they can't say anything legally about it), however, setting a static IP address in the same range as your computer at school may be against their TOS which you abide by being on campus. Let us know how everything goes.

With Static I set an IP and all other info (Gateway, DNS, etc, except for Network Prefix Length... no clue what that is, left it at 24 default), and could not ping gateway
Dynamic/DHCP I will have to check tomorrow, after downloading stuff for the tablet to get that info (I think I need root to use IfConfig with Terminal Emulator, correct?).
Whatever they use to block me out, it seems to have a slight hole built in... every day, multiple times a day, I will look down at my tablet and see notifications (mainly email, occasionally Facebook, etc) that pushed through on the schools network (I know that for sure, being that often times the emails are messages received during the day, in a time period where the tablet has been nowhere near any other networks). Maybe this hole can be breached?
Thanks!

It seems like small gaps where the system doesn't block you long enough to receive some traffic, but that is promising. BTW, you can get your "network prefix" (netmask as we call it) from your computer. If you go into the command prompt on windows and run "ipconfig /all" you'll get 4 useful bits of info we need, IP address (so you can mimic it), the gateway, the subnet mask (usually 255.255.something.something) and the DNS servers. The subnet mask determines what you use, and I HIGHLY doubt they use 24 (that's mainly for home networks, 24 = 254 devices permitted on the DHCP, 16 = 65534 devices (this is WAY more likely)).

Well, I just had a clean connection for about 5 minutes, and had a normal-looking IP based on my PC. Using Terminal Emulator I pinged the gateway after my connection failed, still with no response. I still appeared to have a proper IP on my tablet, but no actual internet connection.
So, perhaps these small windows are something to pursue? Or perhaps sticking with the VPN plan is best?
Thanks!

You need to make sure your networking information is entered correctly, you still haven't said anything about the netmask in this situation. However, if you're entering this information in correctly then you should have a solid connection until they realize you've forced a device into the network. The only thing you can do beyond that point is during that window, open a VPN connection without using a single browser request so they don't know what the device is unless they check the MAC address. Either way, this is a window that can be used, you just need to avoid identifying your device in any way prior to initiating the VPN connection. Turn off Sync when you connect.
