I'd forget there is any WiFi when it's in a basement. There are so many web pages about this that I will not duplicate it again. If this was mine I'd move the router WiFi to old reliable 802.11g mode ONLY and pick a channel. Now that should get you coverage in the basement.
For upstairs I'd deploy another WAP (even the 20 buck TL-WR702N will do then for starters leave it on 802.11g and another channel to spread the WiFi load.
-> TORRENTS mean the death of a network. Not only do they suck up all bandwidth but can cause DOS attacks. If you want this to work, you won't go near torrents.
Yes there are some that can't kick the habit so they can't be helped,
I've been having some trouble with my network as of late. It consists of:
2 GB wired computers
2 100Mps wired computers
3 wireless laptops
3 wireless phones
1 wireless printer
2 wireless game systems (Wii/PS3)
1 wired NAS (DNS-323)
1 router (DIR-655)
1 cable modem (Cable. 55mps service... unlimited)
1 9db wired extension antenna
I have been having issues with wireless transfer speeds and internet speeds. The router is in the basement with a line running to a 9db amplifier upstairs. The NAS is also in the basement.
Running of the router is:
2 wired computers
1 NAS (DNS-323)
1 Switch (Switch A)
Running off of Switch A is:
1 wired computer
1 switch (Switch B)
Switch B goes upstairs and has 1 wired computer and the PS3 (although the PS3 has not been switched to wired just yet. My son is working out the details.)
Transfer speeds between the NAS range 12-18mps. the same goes for the computers.
Wireless? Luck if I break 1mps.
Now... As for internet... what a cluster-bomb. If I deny access to all computers and devices and only have my main system (GB Ethernet) I can crank out internet speeds like nobody's business. Torrents running at 6.5mb/s and still browsing the web without lag... As soon as I add ANY device... even the wireless printer... I can't break 500kb/s with a torrent and it locks everyone's internet up. Useless.
is it possible the quality of router is too poor for the service provided? Or perhaps it cannot handle so many devices? At any given time the three phones are connected as well as the NAS all the time... Maybe 3 wired computers.... The printer is usually on full time..
I intend on getting a smart TV in the near future. It will be wireless as well. There may be 2 by the end of the year. And a wireless IP camera system has also been considered. So if I need an expensive router to handle all of this I will gladly shell out some $$$ for it... But is it my problem to begin with?
