I received a TP-WN882ND wireless card on Friday and installed it into my emachines computer. On Friday it connected to my router with no problems and i was able to go online all day. When i went to use the computer on Monday morning there was no internet connection. When i try to search for my router through the Tp Link it does not find my router. I originally thought that the wireless cards were not working but then i re-scanned and found that it can connect to MetroCast across the street. I would be more than happy to use metrocast internet and be done with this mess but they have a password block.....If anyone can help me that would be much appreciated.
