Linksys Router giving wrong IPs

[Boughetto]

What's crackin folks,

Here is the deal... I just set up this network and everything was working fine but then I noticed that the router was giving bogus IP's.

I have a Linksys router, WRT55AG, with a hub, connected to a T1 line. The settings are on autoconfiguration DHCP so that should spit out a proper IP. When I correct the problem, everything will work, print servers and everything on the network runs great, but come the next day, everything is down. I ipconfig to see what IP I have and it's giving me a 169.xxx.xx.xxx vs. the 192.xxx.x.x I should be getting. I'm running XP and I have all fields correctly filled in I hope... heheh. I already downloaded the latest firmware for it and I've gotten to the point where it will work for awhile then go back to this bogus settings. If anyone needs anymore info please let me know. Much love to y'all for the help!

I could be way off on this but I will try I think 169.xxx.xx.xxx is what windows gives itself if no DHCP lease is available. I wonder if your DHCP leases are set to expire too quickly or if the date/time is incorrect on the router assuming you can set it at all. Hopefully that is a little help

how many computers are on the network?

also how are you plugging a cable/dsl router into the T1 line?

do you have the latest drivers for the network card?

I think 169.xxx.xx.xxx is what windows gives itself if no DHCP lease is available

You are correct!

169.xxx etc is not from the router..it is from windows.

It's called an "APIPA" address...."automatic private I P Address".

When a comp cant get to a dhcp server it will just generate an apipa adress in the 169.xxx address.

So for some reason that comp is not reaching the router.

From that comp try to go to a DOS prompt and ping the router.

Do you think if I shut that function off through the registry IsAutoConfigurationEnabled being 0 will fix this? I've tried pinging the router and it misses all the packets. There are 4 computers plus a print server. I'm going to download the latest drivers for the network cards to see if there is any change. If you have any other suggestions, please don't hesitate to drop some knowledge on me

The wrt55ag - that's a wireless router, isn't it? In which case it sounds like it's the wireless connections that are the problem.

I don't know much about wireless technology, so I'll leave it up to the experts...

[Boughetto]

Yes... it is a wireless router. Has capabilities for both wireless and hard lined. Currently I only have wired throughout the office.

I don't want to worry you but a review on the Tech TV site mentioned that a firmware upgrade knackered the router:

under the paragraph that says "Some Features Lacking".

Which would be a shame if it's true, that's a pretty good piece of kit...

Is there an option to configure the router manually, or maybe you could dispense with DHCP and use static IP addressing on your LAN?

[M_Six]

I agree with Eraserhead, with so few PCs on your LAN, go with static IPs. It's a lot easier to track down problems if you know ahead of time which PC has which IP.

[Boughetto]

Excellent, thanks for the good info folks. For some reason the thing wants to work now and I haven't had any problems. Guess it was nervous about the new office Thanks for the inputs again.
