Help! I'm using a WRT54G as my firewall/router on a TW Cable connection. I have a PC wired to the router & a laptop that is wireless. Both connect to the network & access the internet fine. I built a new HTPC with a Shuttle case & HAD to use a WUSB54AG to connect wirelessly. I can connect to the WRT54G router & see all of the shared files on the wired PC & laptop, but this WUSB54AG will not hit the internet. I'm using DHCP on the router with IP's with a range of 100 - 104. I'm using WEP security & also MAC filtering. The WUSB54AG can hit the network. I also decided to use Windows XP (MCE 2005) to control my wireless access (like on the laptop that works fine). I also do not see ANY firmware upgrades on the Linksys site. I called Linksys tech support & they were no help. I also do tech support for a living, but not a networking pro & I'm new to fairly new to wireless. I cannot figiure out what I'm doing wrong. Please help & thanx in advance!
