And the wireless has no end to its issues, first off theres a huge asymmetry in the performance

It seems to drop not matter how close you're to the device at random, Sometimes its filled with DNS errors and the only way to fix it is to toggle the wifi connection.
Latency is all over the place.
Please note my PC is bridged to the wireless via an Asus RT-N16 running OpenWRT and I'm 100% certain this isn't the issue, infact it ran perfectly fine about 4 months ago when bridged to a Orcon Genius while being inside a sleep out made of metal.
I've tried messing around with all the settings I can find, disabling DECT phones in the house.
Superficially my neighbours connection has better signal, despite being further away and probably through more walls.
