Some folk use the WAN port on the second router and you get two networks. Fix? (google this)
How to use a router as a WAP.
Hi,
I currently have an old virgin media wifi router set up in the house to function as a wirless booster which is connected to my main router.
While connecting it to my wifi devices it comes up as a separate network.
Is there a way to set it up so it just exstends my wifi rather than coming up as a diffrent network.
Thanks,
