I have a Linksys / Comcast Wcg200 cable modem / switch / wap.

I have a couple questions about WEP 128bit.

First off, is there a limit to how many computers / clients can use 'Key 1' on WEP 128? When I try to generate a WEP key in 128 mode, it only creates one key- however if you do it in 64bit mode, it creates 4 separate keys.

I am trying to get three computers to use WEP 128bit, but it seems I can only get 2/3 computers to connect.

The main problem I have is actually a DHCP error. The last machine I try to connect (with the proper key / pass phrase) only gets the 169.254 IP instead of a 192.168.x.x. I called Comcast tech support, but they basically just said to use MAC filtering (which I already have turned on).

A follow up question comes by the equipment I have, the damn 3-1 box from Comcast. I can't seem to find it listed anywhere on Linksys's website for updates for firmware. Are firmware updates even legal on a Comcast supplied box?


Disclaimer: I am aware WEP is not very secure, and plan to eventually buy a WPA access point and have the machines go through there- it just might require some time.

Thanks in advance,
Moose
 
not sure on the wep aspect of your problem sounds wierds. on the comcast modem there shouldn't be a need to update the firmware and as far as i know you cant. might be wrong though.also go to your local area connection, check your tcp/ip settings and make sure its on obtain an ip address. you should be getting an ip address of 192.168.x.x that the linksys should give to you
 
you can't update comcast gateways and comcast limits the number computer you can have to 5. how can you log in to the router? if so see what the dhcp server is set to. it may be set to only let 2 computer on
 
Thanks for the responses, I can log into the Comcast box. Comcast puts a limit of 5 IPs that it allows access to the net. However, right now, all three boxes are working great- except that there is no encryption. Just MAC filtering. It’s a pretty strange problem, I know. =/
