Ip address problem 169.254.x.x can't connect to wifi network

[willpower102]

I'm currently running wm5 ivan w/rd
i keep having this problem where i try to connect to a network, and it connects, but i can't do anything.
When i open up my ipconfig it shows the network ip address as 169.254.x.x where x is always something different. My router shows the mac address on the network but it's unreachable.

Does anyone have any idea where this ip is coming from? I've tried different radio versions, and it happens so far with 1.1.13 and 1.1.15 on both wm5 AND wm3.

169.254.xxx.xxx is a class of ip addresses set automatically to a device, when this can't connect the dhcp server. is a reserved network.

if your router is set as dhcp server, you must verify the link connection with pda. else you must configure the correct ip address manually to the pda.

download and run vxIPconfig and use that to release and renew a new IP from the DHCP server

Nine times out of ten this is caused by bad encryption settings. If you put in the wrong WEP key for example this is what you would see. You don't get error messages when it's wrong, which is kind-of by design and desirable for security reasons.

I'm downloading vxipconfig right now. I did a search last night and was reminded of 169.254.x.x coming up on machines when winsock is corrupt.

Another web site said something about how a pda will connect to the first computer with activesync through wifi under this ip address and try to sync, and then it will get a normal ip address. I don't know if this is true with this device.

@closer what do you mean verify the link connection? The router shows the pda's ip address in it's connection manager, but for any computer or pda i don't know a way to "verify the link" other than look at it. There's no command for this. The router is set up to correctly assign dhcp as i have 2 computers and 2 xbox's connected through lines, and 2 computers through wifi. I know i can manualy set the ip, which i often do for everything but the laptop, but this is a pain in the ass to try and find out the gateway of every single router when i'm out in town. That's a workaround, not a fix.

@Black6spdz I was using Myipconfig and it would release and renew to just a different 169.254.x.x. I'm going to try vxipconfig when this happens again.



--Well, last night i got pissed and abandoned working on it. Low and behold when i wake up today it's working fine and has the correct ip address. That sucks, because now i have no idea what was wrong.
so...
-It's time to go connect to some other networks and see if it resolves correctly.
-Then i'm going to go through the 3 different radio versions and see how they affect it.

when I had that problem it was because my settings were set up incorrectly.. If i were to use gprs, it'd work fine. But wifi would not. So i had to make a seperate setting with generic entries and not set up proxies. then wifi would work. sort of a pain. but it would work...
