Ok, have been running on Sky Max for about two months. Generally have been really pleased, only problem has been the poor wireless signal from the Netgear router (I live in a Victorian basement flat- walls about a foot thick = low signal!). Girlfriend was hassling me last night over it as her Mac couldn't get online so decided to hack Netgear (Sky) router, find username / password and try using 3com router.
Did this with no problem. Didn't actually flash Sky router, just probed it to supply username and password in a .cfg file. Entered this into the 3com router - no joy. Manually set the IP and DNS according to the Sky router - et voila! Worked perfectly!!
.... for about 1 or 2 hours.
Suddenly - nothing, the connection just went dead.

Tried switching back to the Sky router - still nothing. Tried restoring old settings that I'd backed up from the Sky Router - nothing, "error" on attempting to backup. Tried to flash the router with the Sky firmware flash provided on the Sky Broadband CD - the firware upgrade can't see the router (either over wifi or CAT5 Lan).
Tried tech support - "Error 300" on connect / disconnect - escalated to T3, 5 day wait..
Any idea what's happened here? Why would BOTH routers suddenly stop working? This suggests it's the line, not the router. Any ideas?
Has been on the master socket overnight, no connection this morning (although show up/down speed info). Often report 16MB downstream and no usual problems with drop-out. Will post snr, attenuation etc tonight from a friend's house.
Just felt like Sky had blocked the connection (perhaps because I was attempting to use a 3rd party product) rather than this being a technical issue, but no-one else reports this type of thing, so no idea what's going on. Could it have something to do with the fact that I used a fixed IP on the 3com router, SKY cycled this at some point during the two hours when it was working and now I've locked myself out?
Thoughts, anyone?
By the way - superb forum / site - especially thanks to all Sky people who bother to help on here - it's appreciated!
