I have 2 wired desktops and 1 wireless laptop connecting to the network. My DSL internet connection does not go down, my wired desktops are fine and connected to the network.
I have the wireless set up with a 128-bit WEP key, Open System. I have set up the laptop with the same profile and it automatically connects to my network when I turn it on. It reconnects automatically when I reboot the laptop. However, after the laptop has been off for several hours (overnight or during work hours while I'm away), I turn it on and it says "unable to connect to your preferred network" or something similar.
It sees my network in the list of available wireless networks, but it will not connect (either automatically or by telling it to connect). The only way to reconnect has been to take these steps:
Go to the router web interface through a wired desktop, and re-enter the WEP key (13 character string for 128bits) and re-enter that same key in my laptop. It is as if the router 'forgets' its WEP key and I have to set it up again.
I have 802.1x authentication turned off on the laptop (I know that causes disconnects)
I have read many suggestions here about dealing with similar but different problems. Changing the channel from 6 to something else, turning on '4x support' and/or MAC filtering (these are disabled - I don't know what they do).
I am debating whether or not to cancel Verizon DSL and go back to more expensive Comcast cable.
Please help, this is very annoying. It is not easy to reproduce the problem because it happens about half the time. I have to reset the WEP key on the router and the laptop everyday. Internet connection through wired computers is fine. Thanks!
