Surf SOHO Wireless Connection Issues

Hoping for some advice regarding issues with my wireless connectivity. I have two devices that were disconnected from my router for no apparent reason. One is a streaming camera that connects via ethernet just fine but when select the wireless option the device will scan and find nothing to connect to. The second device is my Epson wireless printer which finds my network but will not accept my password. The diagnostics state that I have the printers MAC address blocked but that is not the case.

Will a reboot solve this problem or do I have a hardware issue? Any advice will be greatly appreciated. Chris
