on the locate network, can you access the camera by IP address:port? like 192.168.1.X:XXXX?

Have you tried this: uninstall the driver and utility. While reinstalling the adapter, only install the driver without the utility, and use Windows wireless utility to connect the wireless network...

It does not seem to have this option.

1 you can try to factory reset and reconfigure the modem 2 change the channel 3 how many client devices are there connected to the modem? 4 what kind of device do you use for WDS or universal...

you can go to the tp-link website to download a tp-link firmware and upload it to the router. http://www.tp-link.com/en/support/download/?pcid=201&model=TL-WR841ND
