    Hi there

    i'm a little confused, any advice would be much appreciated.

    i live in a fairly large house, and have recently set up a wireless network. i use a D link DIR 635 router and a Intel WiFi Link 5100 on a Dell laptop which is only a few months old (the router and laptop were bought at the same time direct from dell). the wireless conection in general can be pretty temperemental, the laptop doesn't seem to lose the connection altogether, it just goes to 'limited connectivity' and i'm unable to use the internet. the problem becomes worse when i'm further away from the router. i understand that the connection will be worse the further away i am, but the signal strength indicator is still showing good / very good / excellent but the internet connection barely works. i really don't understand. i'm pretty sure it's not the internet connection, as on the pc that's wired it's fine. i thought that if the signal is showing as good, then there shouldn't be any problem connecting to the internet as the laptop and router are talking to each other - this doesn't seem to be the case. i specifically bought this router and upgraded the wireless card to use 802.11n as i read that this would work further away. as you can see i'm no expert!

    any advice would be great, i'm not sure if i've provided enough info to understand the problem.

    thanks a lot

    **** sorry i should have made it clear that the connection does work sometimes, it's working fine as i write this. that's the strangest thing - the laptop can stay in exactly the same place - with the signal quality indicator thing staying the same - but then just go to limited connectivity. it then sometimes starts working again. i would have thought it was the sort of thing where it either works or doesn't??

    thanks again guys

    Some things you can try here in order of their possibility of solving the issue.

    1. For wireless connections, change the channel on the router, I like channels 1, 6, and 11 in the US.
    2. For wireless connections, try moving either the wireless router/AP or the wireless computer. Even a couple of feet will sometimes make a big difference.
    3. Update the firmware to the latest version available on the manufacturer's site.
    4. Reset the router to factory defaults and reconfigure.
    5. Update the network drivers (wired and wireless) on your computer to the latest available.

    Many times these measures will resolve a lot of intermittent issues.

    Just want to stress number 5 above and suggest you do this first; get the latest wireless driver from Dell's web site.

    And, if you are using WEP encryption, try unsecured or WPA-PSK.
