I use a Netgear WGT624 which I bought off eBay years ago as a reconditioned unit (cheap) and has always worked faultlessly.
Don't have access to router ( I don't even know where it is)
I need something similar to this. Tried about 4 different routers and with none of them will the wifi signal reach our lounge. Fine everywhere else in the house just this one room. Would I wireless range extender solve this? Does it matter where it is located? Closer to the original router the better?
