Internet seems extremely slow atm... nearly 100ms ping to Auckland speedtest servers and total bandwidth seems to be about 250 KB/s or perhaps less.

Am getting occasional 400 Bad Requests with pinkish backgrounds in the modem back-end but sync stats appear normal

Could it be my modem going bad? It's a Netcomm NB6Plus4Wn and it also likes to crash/restart when I overload it with torrent connections or loading many various tabs
