I had plugged in the GLB-502T to check out its web interface (haven't got my ADSL connection activated yet :-( )and I found my system becoming *lazy*.
In the sense that applications were taking a longer time than usual to start up. The system indicator applets show no activity - CPU, memory, disk or swap - no blinking HDD LED - but there is a noticeably large lag between clicking an application and it being ready to use. So much so that it took almost 5 minutes for my desktop to load after login.
Removing the router and plugging in the cablenet LAN brought things to normal.
Another thing there seems to be a lot of bad karma associated with GLB-502T. http://www.webservertalk.com/archive236-2006-9-1667246.html Plus there's a bunch of posts on <www.broadbandforum.in> (it isn't working as of 11:20 AM today) that I came upon stating some problems to do with its WAN MAC address.
Anyone on this list with experience - good or bad - of the GLB-502T?
Regards.
