i always found wifi to be trouble with all my gadgets and wifi capable things. for example some work better then others and there in the same place, i change my wifi settings a little and it's the other way around or 1 doesn't work at all. check things like what band it works bad or not on on your router if you change the settings. are there other wifi networks on the same channel or 3 channels off etc. an example would be turning on my ps3 and the laptop cant see the wifi network but everything else can. there anyone with experience with wifi and chips etc who can advise?
