I built my network infrastructure weird so all the wireless bands (A, B, G and N) all have individual access points so that if one goes down, the rest are not buttfucked and you can switch over. I regularly use all the bands but N and my two other roommates normally use it. It's done using a TrendNet TEW-630APB access point. The complaint is that this access point is lossy as fuck and while my roommates discusses conspiracy shit on skype, watches another free energy video in 1080p or cyber fucks with some draconian avatar slave on Second Life his connection will drop. I switched the access point to G/N mode so I could use my laptop on it and I wasn't at least having issues with G. I opened the unit, repalced several capacitors and threw a heatsinnk on the main IC's plus relocated the access point on top of my living room shelving so it's at the highest point in the house and even then he's still having a bitchfest because he can't get a decent connection 25 feet away in his bedroom. He finally invaded into my realm by replacing my fucking WRT54G with some shitty D-Link router/N access point piece of shit that fixed his problem but buttfucked all my router configurations that can't be copied from DD-WRT to this shitty D-Link firmware AND suddenly half of my systems no longer have working HTTP internet connections (but oddly, everything else works and connects :/).
I can get access to a USB N dongle to test with but I need to see myself just how touchy this access point is or if it's his fault that his shitty wi-fi card in his ASUS i5 gaming laptop is the fault because he's neglecting the gigabit line I wired into his bedroom. Is there some piece of software I can get that will stress test a wireless connection?
Also, I hear that even with DD-WRT, the WRT54G's are poor performers with torrenting. If I forced everyone in the house to use utorrent and configure it to go through a port forwardrd connection, would that offload things for the router?
If the same router is broadcasting all the bands then if one goes down, all go down, and it will run at the slowest band's speed. Unless of course you have a simultaneous dual-band router which can separately use 2 bands becoming two access points. Best to stick with G or 2.4Ghz N, not the shitty 5Ghz N which can't penetrate a tissue. If you really want to test signal levels try inSSIDer, it shows a graph of signal strength and channel. Make sure the channel is 1, 6, or 11 and if neighbors are close by and using those frequencies then that sucks. Avoid shitty dongle adapters that have no external antenna, and it's possible to purchase larger antennas for some routers. If you're having trouble with connections try connecting one access point to the other through one of the switch ports, and turn of DHCP on the second point. The first router should worry about assigning IP's while the second acts as an access point. Basically connect his router to yours. Or for fun connect his router to the gigabit line in his room.
I own a Wi-Spy so I was able to do all that stuff with seeing who was using what channels and what the spectrum looked like. It already included inSSIDer. All my Access points are fixed to work at separate enough channels that they don't interfere with eachother or the neighbors. B and G are 1 and 6 respectively but the D-Link is at channel 149 (5.745 ghz) so I don't think that will be much of an issue.
While I do use that WRT54G, I do not use the internal switch or wireless for reasons. Internet goes in and out of it and everything on the network connects into one 16 port gigabit switch.
By the way, I found out how to disable the DHCP server on the D-Link so I forced it to act as an access point and put the Linksys back in as my router.
