  • Assignee set to lynxis

I ordered a GT-B2100 via ebay so we can reproduce this in the lab.

  • Assignee changed from lynxis to roh

roh: The task here would be to set up a (mostly) current network from nightly packages, use the GT-B2100 that I bought and try to reproduce the problem. If you can reproduce it, please create pcap + log files and attach it here.

tried to find the phone today - no luck... did it arrive?

#7 Updated by laforge 2 months ago

This is sad. The phone definitely arrived back in January but it seems it has disappeared meanwhile :( I've now ordered yet another one on ebay.
