WiFi Hotspot IP change?? - Vibrant General

I use my phone for a WiFi hotspot and sent the signal to a Wireless WiFi router to get internet to my Desk Top computer and my FTA satellite box. I was just wonder, if I turned off my WiFi hotspot and turned it back on would the IP Address change at all or would it be consistently the same??

Leased IP Address

As I said, I run my computer from my cell phone wifi hotspot and when I turn off my wifi hotspot and turn back on the IP Address seems to stay the same and MOST IMPORTANT, my computer does not show how long my IP Address is Leased for. Is that a good sign, which means that the IP will stay the same and not change every time I turn off the wifi hotspot. I really need a constant IP and was just wondering. I have unlimited data on my cell and trying to save money on the cost of internet, like many of us. Thanks for any help.

Well, if you're on T-Mobile you don't actually have a publicly routable IP address. So you may think that you're getting a consistent IP from your phone, but you really probably aren't to the rest of the internet.
Of course, if you truly *need* a stable IP address (ie for hosting something), then you should at best pay for residential DSL/Cable (which are still dynamicly assigned IP addresses, but have long leases and typically reassign the same IP address to your modem's MAC), or business Cable/DSL which guarantees your IP address will stay the same.
Having expectations of that sort of thing on a mobile network isn't going to be very helpful.
And that said, if you're trying to use T-Mobile as a home internet replacement, you're probably going to start complaining in the "5GB data cap" thread pretty soon. Please don't waste your time. Switch to Sprint if you need unlimited. You'll at least get a publicly routable address, and it may even stay consistent. If you really need to "save" money: sell your phone, transfer your line to someone else, get on prepaid and use the savings to pay for basic DSL.

hotel room without wireless

Anyone know how to convert CAT5 Cable to wireless in the Hotel room. I love to bring my PDA with me , when I travel. But, I found a problem to using the internet in most of the hotel.
Problem: Most hotels only have CAT5 network , when you plugin your notebook computer, you have to go to the login page to login. But when you using PDA(wireless). The question is how to use the internet?. If you bring a wireless rounter with you. When you plugin . how to make it found the hotel login page on your PDA?
Easiest method is to buy a Wireless bridge. Linksys sells these. Its a device that will tern an Ethernet Cable into a wireless signal.
I travel a great deal and although there are a great number of ways to deal with this issue...this is how I get around it.
I bought one of the little Dlink pocket routers like this one for a great price (less than $30). What you can do with this product (and others I'm sure...) is clone the MAC address of your laptop's ethernet port. Basically...it'd work like this...
1.) Plug your laptop into the hotel network.
2.) Jump through their proxy hoops to get out onto the net.
3.) Unplug the cable from the hotel network and into the pocket router.
4.) From the router's config pages...set the NIC to clone your laptop's MAC address.
5.) Plug the hotel network into the pocket router WAN port.
Badda bing! You're sharing their network wirelessly...doesn't take a lot of time at all. I've really enjoyed the Dlink one I got...small...flexible...and it comes with a nice travel case. Linksys (or Cisco now), Apple, and others all make similar products and some of them have the benefit of not needing a power adapter and just plugging straight into the wall outlet (a big benefit IMHO), but I can't speak for exactly what kind of functionality they provide versus the Dlink product as I've never used them.
By the way...a bridge will not help you do what you want...you need at least an AP...but if you get one of the devices like I mentioned...you get the added benefit of a NAT firewall between your device and the hotel LAN (which can be a very good thing by the way).
I can't see why you can't just plug in a standard access point via the WANport. Set the internet connection to Automatic DHCP.
Then the first time you access the net it will be ready for logging in.

Because many hotels control access to their internet connections by utilizing various methods but most often by controlling access via MAC addresses. Think filtering a wireless connection by only allowing certain MAC addresses... Now...if an AP allowed MAC address spoofing...then I certainly don't see why just an AP wouldn't work just as well (other than the fact that you don't get the benefits of a router).
By the way...this topic is certainly not Hermes specific and should likely be moved to a more appropriate forum.
One note should be made.... If the hotel is using NAT to assign IP addresss, and you use a second NAT with your router... you may not be able to use various VPN clients. Double NAT'ing doesn't work for many IPSEC VPN clients. i.e. AT&T NetClient
A number of switch vendors offer the ability to limit each port on their switch to allow traffic to one MAC address per port. A bridge would show multiple MAC addresses and typically when the switch sees that, the port is automatically shut down. This is done in many cases where there is a $10-15 a day charge for internet access and the hotel doesn't want you setting up an AP to share the cost with your travel mates. Thus they limit to one MAC address per port. The router solution would show up with only one MAC address... but you then have the double NAT issue in some cases. If you are not using a VPN, that may not be a problem.
Just some additional data points to consider.
I love the linksys travel router - more expensive then their mini router (about the same size) except for 2 things that are key for me. First, it's powersupply is embedded and 110-220v and 2 - it let's you connect it to a hotel wireless hotspot and then share that hotspot over wifi. This is great - it means that 4 people with rooms next to each other can share the fee of the hotspot and share it. It also means I can share that same hotspot with my phone! The only downside on this one over the mini router is it only has one wired out jack but that's no big deal for me!
Note that plugging a router into a network jack when the site in question is set up to use DHCP can cause some havoc on the network. I doubt many hotels are savvy enough to start hunting around for rogue routers when people in the hotel can no longer get IP addresses, but bear in mind that it's always a possibility. It's probably not a good idea to leave something like this plugged into the network longer than necessary.
Also note that whenever I've encountered a location where the establishment requires you to log into a web page in order to access anything, I've had no problem doing that from the Hermes.

The one I mentioned only asigns an IP to people on it's end and not outside - it even uses it's own IP range. It is designed to be transparent to the existing network.
Yes, I know. However, depending upon the network setup, this can still cause problems.
For example, some versions of Symantec's 'On Command/CCM' (a suite for pushing software updates to computers automatically when they are booted on the network) can communicate with some routers in such a way to where the router thinks it needs to try to provide one of its IP addresses to the network. This invariably ends up having a computer in some random place on the network ending up with a 192.168.x.x IP. When an admin sees this, he/she knows that there is a rogue router on the network.
Alot of work... as you know these hotel internet connections are controlled. If you're posting here use that 3g or even edge instead of giving the hotel your credit card to have a field test (is that a ppc program?) or field day with.

Well I doubt this will happen in most hotel networks and aside from that - I doubt that there is hardly ever a network admin on hand 99.9% of the time
The Linksys Travel Router is the product I'd highly recommend as I've been using it around the world for some years now.
It has a hardware switch that let's you control its functionality. In one position, the Wired Ethernet is simply converted to Wi-Fi and once you connect, you still get the IP from the hotel's DHCP server. If you need to share the connection with more systems (such as your laptop and your phone or with some colleagues in adjacent rooms), you just switch to another mode after logging in to the hotel's network and the Linksys becomes a NAT router and gives you a private IP.
It also comes with a nice travel case...

That's the device I've been talking about - the only thing I add to the kit is a european outlet adapter (which fits nicely inside the coiled ethernet cable included

Wi-Fi router

All
I have my htc setup to both internet sharing and Wi-Fi connection on my work PC with a lan connection. On both of these connections e.g. wired USB and wireless i can get the internet for about 3 minutes then it stops working. Is there some sort of block? I did see a while back that the WiFi app has no restrictions...
Any help would be superb.
Cheers
Baker0
Thats a little odd, there is certainly no block and I have had the wifi router running for a good 30-40 minutes without failing.
what part is failing, is the phone no longer running the wifi router, or is the pc no longer getting internet on that network connection?
If you need help on how to find this info just reply and I can walk you through some more diagnostic steps.
The phone is still running just the internet stops on the machine. I have to stop the wi fi on the phone then start again then connect. I think it might be t-mobile but the internet on the phone is fine
are you in the uk?
if you connect your laptop to the phone via the wifi router you should be able to right click the network logo, click on status and view the wifi network info, it should tell you in there if it has internet access on that network connection.
If you try this again and when it fails check this status window and see if windows is seeing an internet connection or not?
when the net fails again try and visit http://72.14.203.100/ (this should be the google homepage) if you see google then there is a dns problem if it still says network timeout or failed to connect or something like that then we will have to dig further.
LOL thanks for your help. I am in the UK. ive been working in IT for the last 12 years and I know and have done the test, its not the machine it has something to do with the phone or t-mobile network
Sorry to hijack your thread a little, but I'm on the T-Mobile Network in the UK too (except I'm using a Touch Pro with a custom ROM), and although I can make connections from the PC to websites using the IP address, the DNS isn't working so I can't resolve domain names.
Any ideas?
Cheers,
Steve.

It must be the phone then since I do use wifi router, I am on t-mobile and in the UK and I do not experience this :S
I seem to be saying this more and more but maybe you should try a hard reset and see if that fixes the problem?

This is likely an issue with the way your machine has been setup to connect to the wifi network. Try visting the properties of the network and vieing the dns settings for the tcp/ipv4, It should be set as Obtain DNS server addresses automatically. If it is set like this then try setting it too 8.8.8.8 and 8.8.4.4 these are googles, dns servers if this works for you then you could stick with this or do some further digging as to why you are not getting the dns server addresses automatically like you should be.

Setting the DNS entries to Google's makes it work, but attempting to get the DNS Server's automatically leaves me with no ability to resolve domain names. How strange?
Thanks for the workaround, not sure where to start looking to fix it properly.

Hey guys,
I am new to this wifi router thing and got the following questions:
1. To be able to use it, you must have data connection with your provider. Am I right?
2. By any chance, can I use this system by using a sim taken out of a prepaid mobile broadband dongle and inserted into my device (htc touch HD)?
3. Once I get connected can I surf the internet/check emails etc from within the device itself without the need to use a laptop?
Please don't mind these basic stupid questions.
cheers

[Q] Is it possible to renew IP address over GPRS/3G?

I'm using a Nexus One (Android) on Vodafone in Australia and would like to know if it's possible to release/renew an IP address over GPRS/3G.
I've tried using netcfg, ifconfig but none of them seem to actually get another IP. If I shutdown data and start it again, I get another IP.
Any ideas?

Did you try turning airplane mode on and off? That may cause you to get a new IP.
In GPRS your IP is decided by something called a "PDP Context" (a sort of "contract" you have with the Network that decides which data service you can access, what would be the speed of your connection (QoS) and your IP address).
This PDP Context is not easily killed and that's the beauty of the thing : when you're in bad coverage or moving from cell to cell, this PDP permits you to keep your data connection (it'll be probably slower but your web page will go on loading when you'll get coverage again etc...)
So in a word, to renew your IP you must recreate your PDP Context and in order to do that your must reconnect to the network : airplane mode, turn your device off/on or cut data then turning it on like you've just said. No other way...
I'm not an linux expert but I think the "renew" command send an order to the network card. In your phone there's not really a network card but these network protocols, so that's why it doesn't work for me...
I'll search but I think will be the same with 3G Networks...

[Q] How can we select which IP/network we connect to the internet

Hi guys, been searching for an answer to this with no luck.
I own both the epic4g and galaxy s4. Both rooted. I use wifi tethering. Carrier is sprint.
The s4 connects to the internet and grabs an IP from IP pool. eg 66.87.xxx.xx
The epic 4g connects to the internet and grabs an IP from IP pool eg 107.77.xxx.xx
they are both in the exact location (my desk). whether I switch on 3g/4g etc doesn't
matter. the epic always gets from ip net 107.xx.xxx.xx and the s4 always
gets from ip net 66.87.xxx.xx.
There is something in the device that is telling it which network to connect to, but
what. I would like to have access to ALL the IPs thru both devices.
Is there an app?
a setting to effect this?
How can I get my epic to connect to the network (IP) that the s4 connects to and vice versa?
Thanks in advance for your help guys

Thanks but either I did not explain this well enough of you are mistaken. I am not referring to wi-fi,
Let me try to clear it up.
When I connect to the internet with my epic, via 3g or 4g sprint network, NOT WIFI,
I get an IP address of 107.xxx.xxx.xxx something like that. I am connecting to the
IP block of 107 with my epic. I switch to 4g/3g, airplane mode and get new IPs
but all within the 107 block of IPs
BUT
When I connect to the internet with my S4, via 3g or 4g sprint network, NOT WIFI,
I get an IP address of 86.xxx.xxx.xxx something like that. I am connecting to the
IP block of 86 with my Galaxy S4. I switch to 4g/3g, airplane mode and get new IPs
but all within the 86 block of IPs.
How can I access both IP ranges/blocks (107.xxx.xxx.xxx and also 87.xxx.xxx.xxxx) with 1 device?

WIFI & Mobile Data Simultaneously?

Hi, New poster so if I've posted in the wrong area please don't bite
I've been connecting my phone to a smart device (miracast-ing 'direct') but as of late the connection has become unstable and generally unusable. I had the brainstorm of using an old router to stabilize the connection, this seems to have done the trick but now I'm unable to access the mobile data as WIFI has assumed priority. Please bear in mind I don't have home internet so the router is being used solely as a go between for phone and smart device. Is there any possibility of WiFi connection whilst have access to mobile data or is this just a pipedream?
Thanks in advance
You can just start a wifi network from your phone, connect the smart devices to your phones wifi and use mobile data normal as internet connection (this is standard if you start a wifi network from phone). You wouldnt even need the router with this szenario, if the wifi signal of your phone isnt strong enough you can connect your router to the phone and extend the wifi with the router.

Thanks for the reply
But creating a mobile hotspot won't help because it doesn't solve the faulty (actually non-existent) miracast connection, plus I don't need a hotspot because only the phone needs internet access. My earlier explanation was probably a bit vague.
My goal is to mirror my phone's screen but to also have internet access solely on my phone.
Phone➡Smart Device➡Display - Can't connect (used to work faultless).
Phone➡Router➡Smart Device➡Display - Connects but no mobile data available because the phone thinks the router has internet access covered.

Creating a hotspot is not for giving the other devices in your network internet access, this is the only way you can use the wifi on your phone with using mobile data at the same time. I dont know why but android devices never use mobile data when they are connected to a wifi network and there is no internet access available. So if you configure your router as a wifi repeater and setup the phone as base station, your wifi signal from phone to router should be good and you can connect your other devices to the router, the phone should see all devices in the same network if you stop the dhcp server in your router and only use the one from your phones hotspot. Should look like this :
Phone (with DHCP) <----Router---->Smart Device---> Display

Hopefully that sort of config is available on my router as it is loaded with a custom firmware from my old ISP provider.

Router ISP custom firmware seems restrictive (no advanced wireless settings) plus WDS is not officially supported.
Possibly achievable but beyond my technical savvy
Thanks for the advice anyways.
