Hello, for everyone. first of all I appologize for my english, it's not always right/corect, but I'm trying to perfect it. I'm the IT administrator of a school and I'm having trouble with a building, actually the WI-FI inside it, i would like to install for the students(100 students in 25 rooms) 2 routers, wich can support approx 100 smartphones and 80 laptops over the Wi-Fi. I installed 2 Tp-Link Tl-WR1043ND routers, but after a period of 20 or max. 30 min the internet connection is down. The signal from the laptop to the router it's ok, because I put on the level 1, the router Nr1, and the second level the router nr 2. On each level i give only the password from the router of that level. I set up so that one router dhcp work with the 192.168.1.1 class, and the second one with the 192.168.2.1 class. Also I set up the wi-fi channel for the first router to 6, and the second routers wi-fi channel to 11. But the problem is still there, after 20 min the network is overflooded(even if I enabled the ICMP, UDP, TCP flood option). The cause I think is that they are to many smartphones, which (when are connected through wi-fi) are updating each one their applications. Can anybody tell me wich router could support through wi-fi so many phones and laptops?

Ps: after I power on the router on a speedtest.net i get a speed of 75-80Mbps download and a 95Mbps upload. after 5 min, drops down to 30Mbps download, and after about 20 min the download speed is in some cases 0.1Mbps download if I can acces the speedtest.net. The signal from the laptop to the router drops from 100% to 60%. Both of the routers are brand new ones, I bought them 5 days ago.
