    Because I only own 1 computer with a dual-band wireless card. My parents laptop, my phone, my netbook, and my printer are 2.5GHz only. And it's unreasonably expensive to upgrade the couple things that could be upgeaded to 5GHz and that wouldn't fix things like my phone that are non-upgradable.

    Also, this could very well be your internet connection as evidenced by a 155ms ping. However you really need to test out the router to your computer ping time first.
    Obviously you didn't read my whole post or you'd see the second test (wired) where I had a 5ms ping. Also I have a home-server that was getting equally bad wireless speed test so it's not my internet connection.

    -What is the ping time from your computer to the AP when trouble is happening?
    To Test this open a Command prompt and type:

    where is the IP address of your router.

    -Also when you are having problems try running a trace route.. To do this open the command prompt and type: tracert

    or if that doesn't work type: tracert

    Put a screen shot of the results of the up next time the problem happens.
    Sure, if it'll make you happy I can try. I did some of those tests though didn't write down the results - I just used it to narrow the problem to wht 2.4GHz segment of my network. With all due respect, I know how to troubleshoot wired networks because I just spent a semester taking a college class on networking and how all these tools work to aquire the test statistics and know how to use them.

    However, I (suspect) that you are either having one of 3 things happening:
    1) You do not have the wireless routers configured correctly to work with each other and they are interfering with each other somehow. I would turn one of them OFF and leave it off and see if the problem comes back.
    How can they interfere if they're on non-overlapping channels?

    Next time it happens I will try turning one off for a while but there's not very good signal between our office and basement, hence an AP in each place.

    2) If you are using dual-band 2.4 & 5GHz, how do you not know that there is interference in the 5 GHz spectrum happening at all? Are those
    channels hard set or on Auto. The 5.8 Uniden phone is running at about 5.815 GHz & also on 915 MHz (one for the base station & one for the handset).
    My 5GHz is doing fine, never had an issue. It's on auto channel.
    Why would the 5GHz phone xmit on 900MHz? Can you cite this somewhere? I'll check my scanner but I don't think they use the 900MHz band. In any event, the 5GHz network and phones seem to be co-existing fine - my problem is only with 2.4GHz so I don't understand why we're talking about anything else.

    I had to force the channel because on 2.4GHz my routers want to use CH11 since that's the fewest neighbors but then it makes our video sender useless. That's why I set them on channels manually.

    3) You are actually (somehow??) trying to run 802.11n in the 2.4GHz mode only.. This probably won't work as others around you will interfere and cause problems. 2.4GHz is trashed for speed these days and only getting worse.
    Well I would agree N should not have been allowed in 2.4GHz but IEEE thought otherwise. In any event, I think the only N device I have is my one dual-band laptop, all others are B or G. Maybe my netbook but I'm not sure if it's running in N mode because the speed says 54Mb/s.

    In your case I would put everything at AUTO since you are having problems and don't seem to know what is wrong, also reset the router & wireless card entirely and get back all the original configurations. Also, try turning the router down to 802.11g/b and see if that solves the problem.

    Also try this suggestion I found on the web, as it appears you may not actually have any wireless inference (per-se)...
    In my case, I have "good" signal according to the taskbar but poor throughput.
    As stated above, I have reason why I didn't use "auto". The APs are basically stock settings - I disable DHCP, set a static LAN IP for the GUI, change the SSID, set WPA2-PSK, and change the channel. Otherwise they're default settings.

    And read about wireless in this chat too:

    If you are still having problems, I would then suggest you start over with your POST and tell us EVERYTHING to start with from the beginning... What is happening, when it happens (time of day, what you are doing, ect), what is in your house, people around you and there networks, your network, ect, ect, ect... Because your thread started out very empty of required info, and I think we are all just mystified as to what is really happening. There does not APPEAR to be any interference - that we can see - that would be killing you currently, but my suggestions above could be happening or help things. Please try them and get back when you find the problem, or want to go over everything, with screenshots of EVERYTHING ..

    I'll see, intermitant issues are always hard to troubleshoot but I'll post back. Since it's coming & going without me touching anything I can't easily declare something a's strange.
