My Roku stick works well, but the current wireless access point is a bit of a distance from it and it isn't working great sometimes. Recently someone new moved in next door and used the same WiFi channels and we lost the Roku for a day until I worked out our channels are being drowned out and changed them. Laptops and phones in the same room as the Roku work ok, but the Roku is pretty small and probably has a tiny antenna. Most of our devices use ethernet, and there is ethernet to right beside the Rokua.
We sometimes use an unblocker for the Roku - not often, but sometimes. Mostly we watch NZ Netflix. I currently connect it to a router a second subnet, which has different DNS servers. I use an old Linksys 54GL running DD-WRT. We don't really have space to put it behind the TV. My wife uses the unblocker from her laptop quite a bit as well, so a WAP is a better option than changing the Roku.
Can anyone recommend a small router, or failing that a small WAP, that might do the job? Maybe even something at looks like a wall wart, with just ethernet going in? I'm thinking more than $30 - $50 cheap ones than the $50 - $150 decent ones, just because it's not worth that much to me to watch TV. I'm fine with ebay / ali express stuff so long as someone has used it and recommends it.
