Cannot get the wifi to work...

do you know where these "hotspots" are actually coming from? Meaning are you trying to connect to a known free/open hotspot, or are you just picking up random wifi signals, and trying to connect off of them.

[Guide for wifi and ipod touch|http://discussions.apple.com/thread.jspa?threadID=1315137&tstart=0].

I have followed this thread carefully but still cant get my 32g iTouch to connect to my home network! It was working fine when I was abroad but now at home, it is a problem.
I am using a BT Voyager 2500V modem that hardwires to two PC's, it also has wireless capability.
I have set the wireless to the point that the network registers on my iTouch but the screen says that the server can not be found!
The little blue arrow reveals the following info:
IP Address: 169.254.xxx.xxx
Subnet: 255.255.0.0
and thats it, no Router info, no DNS info, no nothing. HTTP Proxy is set to off!
Typing ipconfig and/or looking in the router pages fails to provide any obvious answers, so I would really appreciate some help!!

Many thanks in advance!

Hello, I also just got a 32gig Touch iPod that will not connect via wifi, at least not using , however I do have much more success if I use the actual IP address of the site. I do not understand alot about DNS, but I know other iPod users that say that is not right.

Did you get this working yet? I'm having the same problem with my touch 32 GB. I can't access on any networks and the fields don't populate with any information when i look in the settings.

I have looked on several other forums, but it seems like everyone else who describes this exact problem never finds a solution. I'm going to keep trying and if I don't get it tonight I'm going to go back to the store tomorrow. I'll keep you posted if I get it figured out first though.

IP Address: 169.254.xxx.xxx is a common ip address when the device tries to get an address from the router and fails.

DNS addressing is passed along by the router with an ip address for the client device when you connect to the router. This is provided that the connection was set up properly.

WEP or WPA encryptions are great for keeping a Wi-Fi network secure, but it increases the frustration 10 fold for getting small devices like an iPod touch to connect.

Just curious.

Do the people who are having trouble have 802.11b or 802.11g routers? I know the iPod Touch is supposed to support both, but there is a difference between b and g.

I am using a Linksys WRT54GX4, its a mimo router that does b and g. Currently set to mixed for both.

Also I should have mentioned that I am not using any security such as WEP or WPA, my home is pretty remote so I am not concerened with anyone else trying to access it.

wireless B and G are the same, just G is twice as fast as B.

The speed is different, Rob, and that could be why some packets are being dropped. I have had instances where, when I viewed a particular web page at first, I had particular jpeg files missed and, when I viewed it a few seconds later, that jpeg appeared, but others were not loaded.

In addition to the speed, there is a different modulation between b and g. As I recall, b uses an FSK modulation, while g uses quad AM.

Also, b uses DSSS and g uses OFDM.

Not saying these would cause a problem. Just that there are differences.

I think it's also true that, if you have a b/g router, it will downgrade to a b if you have b devices on the network.
