    Home Wireless Channel? Which one?

    Just started to get intermittent problems connecting to my wireless router (via wireless) at home and looking at my wi-fi analyser there are a few on the same channel around me. Could this be the problem? If so can I just select any of the channels (i.e. one that is not being used by anyone) even ch13?
    Its only a b/g router so anyone got any suggestions for a replacement that would big b/g and n which gives good coverage. Its not for cable just broadband via the telephone line.

    Yes, pick one in the clear but remember you will actually span several channels. What analyser are you using? I highly recommend inSSIDer from MetaGeek.

    I would use any of the free tools to look at the channels in use ideal you should use 1,6 and 11. What can happen is people change ISP and use the default box settings.

    This is becoming more of a problem. Five years ago a scan at home would pick up three wireless networks including my own. Today, when I do a scan I pick up over twenty not including my own two. And three of my neighbours are using unsecured WEP which is worrying.

    Yes, that's right - most of the wireless networks around me are Sky boxes with default settings.

    I've got 12 near me, including a BTopenZone accesspoint from the restaurant down the road!

    I just selected one at random and saw how it worked. If coverage was poor then I tried another one.

    Thats the exact problem, its getting very crowded, just changed to ch9 and its connected OK. For wi-fi analysis must admit to using a fee one for my HTC Desire. Works well and gives more info than I understand! (but does graph alot of it for simletons like me :-) ) Could really do with changing to one with n though as video is a bit jerky at times (ok more often than not!).

    On the subject of seurity, what would you suggest the best security to be? WPA2-TKIP? or WPA2-AES?

    Any suggestions for a 'n' router?

    I've never had an issue with channel 11. Sky and BT seem to use the channels lower down the spectrum by default.

    Yes was on 11, and that was busy!

    Just looked at the router security and the only opions I have are WEP, PRE-SHARED KEY or Disabled!! Think its time for a new router with better security!

    Cordless telephones, microwaves and baby monitors also operate around 2.4Ghz. However you won't be able to detect the interference if there is any without a spectrum analyser.

    Racks of CDs and metal coat hangers near to the antenna can apparently cause problems too.

    The last time I looked, the simultaneous dual-band NetGear WNDR3700 was a popular choice because it's fast and supports alternative firmwares such as DD-WRT. As this is only a router you would either need to use the ADSL modem on your current router or buy something like the Draytek Vigor 120 which would sit between the router and the ADSL line.

    WPA2-AES is way more secure and the actual standard, TKIP is an old type and is only included (breaking the WPA2 spec) for a little extra compatibility with old equipment. TKIP is full of holes though so AES is the preffered choice by a long shot. Reading your later post your current one only supports WEP so thats about a half hour of snooping to crack the key. Given the ammount of open ones around though by the sounds of it there are even easier targets around.

    WPA2-AES is better. TKIP is an old standard that is based on WEP and I believe has been recently cracked. A lot of new kit won't support TKIP soon.

    If you live in a very densley populated area with lots of APs (and get on with your neighbours) ask them if they will turn down the power settings on their APs too. Explain that it will make their connection more stable and add a little more security.

    You should def stick to the 1, 6, 11 (or 13 in the UK if AP and client both support it) to make sure that you get sufficient separation.
