I had the hacked firmware in, and the btagent on; so I just realized that I lost the web interface (and thus the way to upgrade the modem firmware myself, I supose)
Does anyone knows how to restore that web interface?

BTW I seems to have gained about 8Mb/s down with the new firmware, however I do have wierd dropouts on my VPN that makes remote screen sharing mostly unusable. I've seen reports that the 'new' firmware have a problem with dropped/blacklisted UDP, would that be related?

Just hack it again using the original method and fw.

The new firmware did increase my line profile slightly.

With old firmware it was at 56477

With new firmware I get 62259

Initially it only went up very slightly but then after a few days it went up a bit more.

Historically my profile has been floating around:
56985
56791

that will explain why I cannot get into the modem now new firmware downloaded it would seem.
