If your DSL truely goes out then you can't control that. Contact your ISP. If your router or PC disconnect at your end at 9PM then thats a different story. Although I have no clue what it is. Other PCs in your house have the same problem or do you just have 1 PC connected online?
the exact opposite happens to me while playing et ...when i play its fine but when i close the game my dsl goes off for a lil whiel and then comes back again.
My friend has a wierd issue with his DSL. Sometimes he has to leave the phone on (dial tone) for his DSL to work, so he says. His cordless has run out of battery power before and then been disconnected. I've seen him log off and then on a few mins later several times. lol
Asus tell yourfriend to get a homerun which is bsically a a direct connection of the RJ34X i believe regular phone cable to the NID. he wont have any filtrs because the dsl line will be connected directly the line and he wont have to worry about other phones in the house or other peripherals screwing up his dsl.
