As suspected your neighbor TheZoo-guest is also using channel 1, this will cause problems because you are also using channel 1 and you both have about the same signal strength. You should go into your routers settings by typing the default gateway http://192.168.1.1/
into your browsers URL, or just click on the link. Admin is usually the default password.
You can then change the channel to channel 6. Channel 11 is also being used so using channel 6 puts you right in the middle for best possible band width and no channel overlap.
You should also remove those static DNS servers from your IPv6 properties, as it could be part of the problem.
DNS servers would go either in your IPv4 properties or type them into your routers settings for DNS servers. Try changing the DNS server to Google's DNS at 126.96.36.199 and 188.8.131.52
That should fix you right up.
