Cons: Very bad signal ranging. I can only get a good and fast enough signal within the same room or without any blocking wall. So, it is not good for a house, which makes this a piece of junk. I have to buy a better ranging router.
Summary: If you can get Version A1 of this router, get it and install DD-WRT and you'll have an awesome router. If you have version B1 you might as well through it in the trash. You'll save yourself a lot of frustration.
Pros: Cheap. Works... sorta
Cons: Version B1 is not supported by DD-WRT or OpenWRT. Without third party firmware the signal is poor and devices constantly disconnect and reconnect. Throughput is very poor.
