My router is in my living room and my laptop is in my bedroom. The distance from the two are literally 10 feet apart.
I currently live on the 16th floor of an apartment building in Shanghai. Now for some reason, I get horrible signal to my router. Even with the door open or closed, it makes no difference.
I think the problem is that there is too much interference. My laptop detects another 20 hotspots to connect and ironically, some of those have a stronger connection signal than my own router.
When I use the WiFi Analyzer on my tablet, I see about 8 connections total. My router is on Channel 5, and the others are on Channels 1,1,2,6,6,9,9. My router is @ 5432 Mhz and -79dBm.
How can I strengthen the signal to my router?
Update: My tablet is constantly picking up new signals. Many routers are on Channels 1,4,9,11

There are more questions about how to improve your wifi signal, so I'm going to only give a short answer, as I currently do not have enough time to look up the other topics.
Wifi should be set to channels 1, 6 and 11, because otherwise you will overlap with multiple channels, and as such your reception will suck.
Note that with channel 11, you will come in the range of wireless phones (dect) so if you have that a lot near you, you are better of at channels 1 and 6.
The theory behind this is that you do not just occupy that channel, but also 2 channels below and above it. So by being on 5, tou are also on 3 and 4 and 6 and 7. Those on 2 are also on 3 and 4. And even those on 1 are on 3. So basically 5 is the worst choice as you will hit every single person connected on the router. Look how strong the signals are on 1 and 6 and choose the best one, or try 11 and see if that works for you.
