Well, not crashing but since we returned from holiday in early September I've been noticing frequent, usually brief connection interruptions on our BT Infinity, which had been faultless. These affected not just wireless devices but the wired PS3 and BT TV boxes too, and affected retrieving music from our NAS array.
So I suspected something inside the house network. I gradually worked out that it didn't happen if I was working alone at home but tended to begin early in the evening, or at weekends. Was there a device or program causing the trouble?
Eventually I dug into the event log of the HH3 and found successions of
out block 65 first packet is invalid (packet not in tcp window)...
with timestamps that matched the times I'd been seeing the connection loss. The IP addresses turned out to be those allocated to the Beestlings' identical Samsung laptops.
This weekend, I tested by elimination and confirmed that having either one connected (wireless or wired) is correlated with dropouts, whereas with both switched off, all is well.
But now I'm stuck. This didn't happen before September, so could a Samsung update (they seem to get an awful lot) have broken something? Googling the message with 'Samsung' turns up nothing useful. Short of banning them from the network, what might I do next?
