Anyone know much about crappy wireless access points?

    I've been experiencing an issue with my wireless connection where the latency (to Google and anything else) gets very high, then goes back down to 30ms when I turn my wireless adaptor off and on again.

    Obviously the ideal solution would be powerline/wired/better-wireless, but before I look at any of that, does anyone have any ideas what exactly is going on here?

    It's a generic Netgear router/modem and a Tenda W54A wireless AP.

    Mine's the one on channel 13.

    I think that the issue in here in is obvious. As we see from the image you posted there is many WLAN networks in your area and they are interfering each other. IF you can change the channel to 14. It might do the trick.

    Could it be some kind of traffic shaping from your ISP?

    If you are on channel 13 I am guessing you have a Wireless N router and a Wireless G card. On my router there are options to broadcast with a wide or narrow band and that might cause issues if the bands either side of your channel are congested.

    Not really an expert so I'm just throwing things out.

    Regrettably, channel 14 is not actually a thing in this context, or I (and presumably others) would be using it.

    That's an interesting point, I'll look into it.

    Thanks to you both for your input :)

    Something I should have thought to try is pinging my router. I get a 1ms ping to my router even when my ping to Google is 2000ms. And yet resetting my connection to the router temporarily improves the latter.

    Inssider scores overlap as worse than being completely co-channel.

    Also, no channel is fully clear, but you are overlapping the strongest - a lot around lower down, but all weaker than that one.

    Thanks for your response, Matt.

    Do you think this is likely to be the source of the issue in light of this:

    When it happens post up a tracert to google, that should show where the leap in ping is coming from.

    I would try channel 6 personally. Does the effect happen across multiple devices or just that one PC?

    Wi-Fi analyzer has a screen that will recommend you the best channels rated by
    number of stars, check your settings/display.

    You have too may Wi-Fi networks in range which will /can Couse issues if
    your overlaps and their too close to you.Can always try being directional
    with your antenna depending on your setup / needs. google "windsurfer
    antenna template" for a cheap directional antenna reflector. If things take
    u down that road.

    As craig recommends a trace route will let you know where the slow down
    is as it can be anything between your Wi-Fi adapter and the server on the
    internet. I've hard intermittent problems in the past usually a router on the internet somewhere being congested or having a problem.

    1st thing I would do is see if their is updated firmware for your router and drivers for you Wi-Fi adapter .

    Thanks for your response. Firmware is all fully up to date on the router and the (driverless) adapter.

    WiFi analyzer says channel 13 is the best channel to go for, which is why I'm on that one at the moment. (It actually prefers 14, but my router doesn't have that option.)

    This doesn't mean a great deal to me. Why doesn't it include steps within my local network?

    Yes. I'm currently seeing 400ms+ ping to Google from the wired PC in my living room. My initial assumption that this was a wireless issue seems increasingly unfounded.

    From the trace route results. It seems to be ISP related. Since the ping is high in their network.

    I feared as much. Unfortunately as the ISP is managed by my landlord, this is the only thing outside of my control.

    Is it solely your connection? or is it possible you're sharing with other flats/households? Are you able to access the router and check who's connected on the local network in case there's wifi freeloaders or any such thing?

    With that bit on info I have a posssable working theory. Could be the ISP
    but also could be someone else downloading or utilizing the internet so
    intensely as to cause this for other users on the same network. It also
    possible to have a something updating or downloading locally that could
    Couse issues like this (ex. background windows updates etc..)

    Thanks for the replies, and sorry for my slow response - I've been on holiday :)

    The router only serves my flat, which I share with one other person. I am able to check who is connected and when, and the problem does sometimes occur when only I am home, and only I am connected. It definitely is exacerbated by background processes like Steam syncing, but getting rid of them does not seem to solve it.

    As for Windows updates specifically, I have them set to "notify me but do not download".
