Help to solve the problem of Wi-Fi

Hebraically, asking for help in solving coverage problems office Wi-Fi em. Now we have LinkSys WRT54GL as a guest, and Vigor 2130n as a worker.
Guest constant problems and have to restart it every 2-3days. Vigor restart is not necessary, but the city sometimes quality falls to an unacceptable level.
Sin on the fact that the routers are connected too many devices (more than 20 in Vigor, and much the same on LinkSys)
Is there a way out of this situation?

Too little information on the status of devices.
Is there any logs hanging LinkSys?
What firmware (stock or DD/Open-WRT)? Is overheated? What about the food?
About the quality of the network — Get inSSIDer and check the air around on the subject of free channels.

20 point is too much. The solution is to put more dots and use the UniFi as it is written here:
A very interesting solution. Most likely going to do based on this equipment. Was on off. website, VIA the controller is available both for Win and for Linux, there is the question of the possibility of installation on FreeBSD. Whether there was at somebody a similar experience? - Abigale commented on October 8th 19 at 02:09
On Win works fine, even forgot about the point) are Working))) - shirley82 commented on October 8th 19 at 02:12

Most likely the channels ispolzuemye router uses nearby wifi access points, turn off auto-channel selection to manual and select another channel at random, determine which channel is more stable.

Also it is possible to overheat the router

The problem most likely 2, which reduces to one.
1. Processor poor router just can't cope with the amount of data chokes. Or the RAM is not enough. Then, as they say, no comments — so everything is clear.
2. Have WiFI is not available, MIMO — Multiple In Multiple Out. It is very much affected if you have very many devices connected to one access point. Read about it in this article:

As you can see, it all comes down to the fact that you have too many devices on one router. So what people suggest is true, you will have to increase their number.
