In my experience, You want something simple that works.
Here is a nice linksys, the newer model of the WRT line
It has about 100 ft of good signal range and is perfect for a small house/apartment for about $40.
Here is another one i recommend, it's a different brand Netgear, but is solid and only costs $35
They both have 4 stars each and the reviews under each one may be helpful. I think either of them would suit your needs.
Both routers are good for streaming. Price doesn't matter as long as its fast and not interrupted.
Both of therse will be fast within the range of 100ft and a few walls. If you want something more powerful try this one:
Hope this helps, let me know if you need any more info
