I know that it's possible to use the Wizard as a bluetooth modem, using your gprs as the active signal.
Since the Wizard supports WiFi aswell, isn't it possible to use the Wizard to connect to a WiFi network and then sharing that connection over bluetooth.
The reason behind this is that I recently moved and we're sharing a wifi connection in this house. But my signal is very weak in my room, but the kitchen next to my room has a signal strenght of over 70%.
I know that buying a better router of signal enhancer would do the trick, but we're poor students
Theory says yes, but I have asked this same question without much luck or a definitive answer.
I have been trying to do the same with a laptop, bluetooth and my lan connection.
Apparently, you need to configure the outgoing bluetooth device, in this case the PDA, to act as a proxy server.
When I linked my laptop to my desktop over bluetooth, it creates a PAN (Personal Area Network). Its IP was set at 169.254.x.x
A LAN networks at IP's of 192.168.x.x and XP wouldn't let be bridge the two together. (Because of the IP differences.)
It would be the same scenario for the PDA.
I am relaying what I have basically learnt but have no idea of which way to take it now so if you have any luck, please let me know.
Pardon me because this isn't entirely a Wizard specific questions although I am able to replicate the problem with my Cingular 8125 (new ROM) 100% of the time.
I'm not a stupid person. I've setup numerous wireless networks for corporations and home users. I always use WEP or WPA and never unencrypted (no) security.
In most situations, the wireless router does NOT supply the DHCP to the clients. It usually comes from another DHCP server on the same LAN segment. Typically, this is a Windows server although it could be a DHCP-assigning device, such as a Cisco router.
PCs have no trouble seeing the wireless network and connecting to it and getting addresses assigned to them. For a while, I couldn't do this on WPA security but upgrading firmware and software on the laptops (usually Dell) rectified this.
With my Wizard, both old and new ROMs, I can SEE the wireless networks and connect to them but I can NEVER get an IP address. It tries and tries and fails and fails and eventually gives up. (Yes, the Cingular proxy is turned off)
Yet, at the airport or other public places with free wireless, I have no problems connecting my Wizard to the access point and surfing away. Thus, I know its not (entirely) a Wizard issue. Of course, these public access points aren't encrypted which could be one of the reasons but I doubt its the only one.
As a test, I just built a new wireless router with a SSID (other than "default") and security turned on (WPA) and let the router act as the DHCP server. Wizard connected in seconds and was surfing away. So the obvious next question is: why doesn't this work when the wireless router ISN'T the DHCP server? Other machines (laptops and such) have no problem connecting to one wireless router and getting a DHCP address from another box yet my Wizard cannot.
I've tested this with D-Link and Belkin wireless routers (consumer-grade).
I've seen other people post that they cannot get their wireless to work on their Wizard and while the fix may not be on the side of the Wizard, I think others may be in the same boat I'm in so I'm hoping that maybe we can compare enough stories to narrow this down so that we CAN use our Wizards wirelessly!

Confusing...
maybe you should try assign a fix ip to your pocket's wifi adapter and see if it would work. or just let the wlan security turn OFF on your access point to see what would happen.
i guess that the network protocol stack is slightly different between a PC and a PPC, which limit the DHCP request route.
I have just purchased the Wizard, aka o2 XDA Mini S, and use it with my Belkin Wireless Access Point (WPA-TKIP Enabled, DHCP & NAT disabled) and Cisco ADSL Router (DHCP Server) without any problems.
I have assigned the Belkin Wireless Access Point a fixed IP address however, but I don't think this would make a difference.
The other thing I found was that the Wizard would not connect correctly to the Belkin using WPA with AES encryption, but switching it to WPA with TKIP works flawlessly.
Well, I suppose its encouraging that others with the same wi-fi routers are getting this to work but its discouraging that I'm having so much trouble!
Fixed IP does work (therefore, its unlikely a Wizard-only problem) but obviously a fixed IP doesn't let me roam from one hotspot (home) to another (work) very easily.
Haven't tried it sans-security yet although that might just prove a point, rather than be a perminant solution. I have tried WPA-PSK and WEP with the same (negative) results.
I personally have found that unless I change the power settings for the WiFi adapter to full power, its hit or miss.
Never have a problem maing connections, geting leases, etc with it there.
YMMV though

prob irrelevent
i found that before i active sync'd. the wireless monitor on my wizard showed a strong signal from the router. then after it synced, it picked up an IP from the servers dhcp fine.
also for lightweight simple security i use mac address filtering on the AP
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
A picture is better than 1000 words.
For an application I'm trying to get this configuration working:
Is this possible or not?
WiFi Tethering to a WiFi Router / Network
Yes, IF your wifi router will accept wifi as an input.
If all of the devices need to be on a network OTHER than your cell phone, then yes, you need a router. The router will have to accept wifi as it's source.
If all of the devices can be on the same wifi network as your cell, then you can get a wifi repeater or range extender. Repeaters "extend" the range that wifi will reach. I don't see that as an issue here as should be able to place your cell phone well within range of your other wifi-enabled devices.
I don't immediately see why you can't have all of the devices connect to your phone directly, but I don't know anything about the application you are working on.
What I cannot say is whether this setup could bypass the number of wifi devices your service provider limits you to. I know my hotspot (Verizon) limits you to five concurrent.
I hope I've answered your question and I've helped. BTW - your picture was perfect!
Thank you for your explanation.
This is a very specific setup.
The router is an Airlink NMini and I carry in my pocket. It has to be near my camera for the wifi connection to work. I get a lot of interference from wireless equipment on my photoshoots. The Wifi router is trong enough to overpower the interference (only when used in B-mode). It's hooked up to a 5 volt power pack.
Close to me I have an Android tablet for quick selecting the right images, then the images are copied over to a remote laptop that is used by my colleage to edit the images.
I needed the internet connection for sending the processed images to a ftp server or dropbox, so my clients can download the images.
I tried using the router as a relay/bridge, but couldn't get that to work. Maybe it's possible, but that's higher networking config.
I finally got it to work by connecting the phone to the laptop using usb.
Configured the laptop for ICS connecting the USB-internet connection to the wireless router. Had to set ip adresses manually, becaue the dhcp of the router did not transmit the correct gateway. But as there are only 2 devices attached, that's not a problem after documenting this change.
So I'm good to go for our next photo assigment. Case closed.

Sweet setup man
I am able to connect to my home router's PPTP VPN server from my Android phone's PPTP client. I can even see my remote LAN devices; and, my remote LAN devices can see my mobile phone on the LAN.
The problem is when I connect my phone to wifi Internet.... BEFORE connecting to my PPTP VPN server... I can't see the remote LAN; and, the remote LAN can't see my phone. The only thing I can do successfully is get a new public IP (my home Internet public IP).
What can I do so that I am able to use my local wifi Internet connection to connect to my VPN at home?
It might be a route problem.
When you connect to WiFi, some static routes are pushed to your phone.
Those routes might not be refreshed or conserved after a VPN connection.
If it is not a route problem it's a default gateway problem.
Yes, that's what I suspected. I already tried adding routes; specifying the gateway via command-line; however, I didn't have any luck; probably because I didn't know exactly what I was doing.
One thing I noticed; when I use my wifi internet hotspot, I noticed that it gets a private WAN IP.. 10.x.x.x; which then NATs to a temporary real public IP; which no connections instigated from the outside world can make it So, even if I do port-fowarding on my wifi hotspot router, it doesnt help any since the incoming connections are stopped dead in their tracks.
I'm using PPTP VPN; which depends on a TCP port 1723. If that TCP connection is instigated from my remote VPN server into my mobile Internet wifi hotspot based LAN devices, it wouldn't work for the same reason explained above. I didn't see a PPTP VPN passthrough option for my wifi hotspot; only for IPSEC; which I dont have a server for. I'm guessing that if I had a real-world public WAN IP for my mobile Internet hotspot, maybe I wouldn't have this problem for PPTP.??

First, are you talking about a free internet hotspot or from private internet hotspot (@work for example) ?
you'll never gonna get a public IP from your internet hotspot. 1-public-IP-for-1-client on a hotspot is just inconceivable, due to IPv4 exhaustion.
I think you only have to try to do port forwarding on your hotspot.
Your assumption "it doesnt help any since the incoming connections are stopped dead in their tracks" is wrong I guess. If your hotspot has a built-in firewall, it might be stateful. As you are initiating a connection to your server, the returned traffic flow shall be allowed.
If it doesn't work after port forwarding, try to look at firewall rules on your hotspot router.
Problem resolved.
My Verizon wireless hotspot (890L) doesn't support PPTP passthough. More specifically, PPTP's routing protocol: GRE (value 47). Verizon does offer another wireless hotspot that does offer support for PPTP; at least via a firmware update.
This issue actually pushed me to install and configure OpenVPN server on my router; instead of using the existing PPTP server which I already had. OpenVPN is fantastic is working through firewalls.
Great !
Yes, OpenVPN is a delight.
me too
I have the same problem,
but I usually change another ROM until there's no bugs

have you tried to configure the wi-fi gateway to match your vpn router?
settings / wireless & networks / wi-fi / long press your vpn connection / modify network / scroll to show advanced options / select static ip /scroll down to gateway and put the gate address in / save
I run a vpn through a 2 router setup, and even though my phone connects to the vpn router, its gateway by default is always the non-vpn router. changing the gateway to the vpn router allows the vpn to connect to the phone. you can verify the vpn connection by going to ip-score.
That why i can't see my phone using wifi in VPN network..
cant connect if theres no mobile data or load
Hi please help ..when i have load i see its connected..but if i have no load its not connecting please ..anyone can explain this?
