[wsfii-discuss] Strange issues with partially functioning wifi hardware

Sun Mar 30 05:47:45 UTC 2014

Issue is resolved

Seems that the ZTE ZXDSL 531B has some problems with the MTU (data packet
size) - someone from another list suggested lowering it - it was at the
maximum 1492 - i lowered it to a random 800 and sure enough the net via the
router is back to normal.

Thanks
