  • Priority changed from normal to response-needed

is this still an issue in current trunk (or AA)?

comment:2 Changed 5 years ago by anonymous

I too had that error a few days ago when I tried to connect my mobile phone via Bluetooth PAN to the router. The DHCP request and response came through, but when I opened a website I got that error. When I reconnected the bluetooth connection, the error didnt appear again for some reason, and now "it just works".

There are a lot google results for "sch_generic" (also look for Redhats Bugzilla Bug 715137).
Well, looks like it happens for a few people but there's no real solution yet.

comment:3 follow-up: Changed 5 years ago by nbd

are you sure it was that error on eth0, and not on the bluetooth PAN interface?

I am using the Barrier Breaker latest code, compile for TL-WR841N v8, and still I got below message which caused us can not access the Internet, this happened on 10M Hub which TL-WR841N v8 wan port plugged in. With some downloading something it just happen, I don't think we should overlook it to the next milestone to fix.
