Question about Linksys A+G WRT55AG Wireless Router

1 Answer

Two Problems with Linksys WRT55AG

I have two issues:

1. The wireless router will fail intermittently in the transmit mode on G but my VoIP connection (vonage) plugged into one of the routers ports works.

2. Vonage device loses connection intermittently...I pull the power cord, wait 30 seconds and plug power cord back in...Looking at the wireless router WRT55AG as the Vonage Device (Cisco ATA 186) is booting up it causes the WRT55AG to continuously reboot until I unplug the Vonage Device Power or unplug the ether net cable to the router..Both the WRT55AG and the Cisco ATA 186 have been flashed with current firmware versions in the past month which was thought to cure the problem but it continues...Vonage Support pointing fingers at the Wireless Router as the problem.....Frustrating on both issues...Anyone have a similar problem or fix...

If you plug in computers on the ethernet ports and they dont light up at all but you are sure that the cables that you are using works as well as the ethernet port on your computer that means that the unit is already defective. You can contact 8003267114 for replacement if its under warranty
