G1/Linksys Wifi Problems

by on Mar.13, 2010, under Networking

Awhile ago I finally upgraded my home wireless network (a single WAP54G v2) from TKIP to AES.  This has been something on the to-do list since I got rid of the Axim (which wouldn’t support AES).  I tested my two wireless client devices – a laptop and my G1, and they seemed fine at the time.  All was well.

Later I noticed that the G1 was not functioning on my home network, yet worked on other similarly secured networks I connect to.  It would connect, obtain an IP address, but not pass traffic – which is a pretty bad scenario since the G1 wouldn’t automatically fail back to its GSM data connection.  I did the typical troubleshooting with “forget”-ing the network and reconnecting, etc, but this was unsuccessful.  More detailed analysis showed that almost immediately after DHCP completed successfully, the G1 would see no traffic generated from the network, and the network would see no traffic generated by the G1.  With the laptop working fine through all of this, it really seemed to be a problem with the G1.

After essentially exhausting other options, I turned my attention to the WAP.  I tried changing the SSID which didn’t help, and reverting back to TKIP, which worked fine.  I then decided to upgrade the WAP’s firmware, from 2.07 (2004 era) to 3.04 (2005 era – still 5 years old!).  The wireless security settings are more granular than the former version – and after reconfiguring – the G1 works on AES.

Hopefully this time it will keep working.
