Hey

Yeh I found the answer eventually, my problem turned out to be a really dumb thing to miss to be honest so might not be the same thing for others.

But I hadn't noticed a new wireless network being introduced into my 'space' (grrr *** neighbours) and basically it lightly crossed with my wireless channel so I scanned the wireless networks to see what channels each one used, found a nice empty gap mine can fit in and then moved it to there and bam problem solved.

God knows what I will do if all the gaps get filled, possible night time sabotage of other networks lol
