One man, two routers
My house has thick walls, so I installed a Cat 5e cable from my D-Link router to a BT Home Hub to get Wi-Fi access at the other end of the house. I disabled DHCP on the Home Hub so that only the D-Link deals with that, and I gave both the same SSID and password.
I get full signal strength and speed wherever I am, once connected, but it can take a few minutes for my Android phone and iPad to connect if I move between the vicinity of the two routers. What could cause this? It’s as if there’s a conflict or confusion from the different routers’ broadcasts even though the SSIDs are the same. Both are set to channel 11, not auto, based on advice from my ISP, and auto-connect to known networks is enabled on my devices. Moelwyn Hopkins This happens precisely because you have two routers set to broadcast using the same SSID. When your devices move from one side of the house to the other there is a crossover zone where both networks are in range and each router fights for the network packets. Instead, give the Home Hub its own SSID, and move it to a wireless channel at least 2 away from the D-Link router, whatever your ISP says. That should work much better.
Manually setting your router’s Wi-Fi channel can reduce interference from other access points.
