Changing the router settings to Channel 11, making sure the SSID broadcast IS displayed/enabled, and by making sure the "Beacon Interval" is 100 or less.
Hope this helps.
I recently set up a network for my father to run a timing system for swim meets. It is a simple network that connects 3 computers wirelessly to a router where an additional computer and a network hard drive are connected via wire. The computers that are giving me a hard time are 2 acer netbooks that connect wirelessly. The network functioned as designed for months until inexplicably the router dumped some settings that I put in place. The system reverted back to a default ip addressing scheme of 10.0.0.X when I had told it to use 192.167.1.x. I had MAC address reservations and filtering enabled with some network printers with static IP addresses. I corrected that headache and everything seemed fine until the 2 netbooks ceased to receive packets but seemed to be sending packets fine wirelessly. The strange thing is that the netbooks have no problem connecting to the network wired. I have checked all of the settings. NIC diagnostic pings come back normal along with running ipconfig. I set the netbooks to a static ip address and confirmed connectivity wired then switched to wireless to no avail. I have also tried WinSockfix, still no results. Both computers are currently set to obtain ip addresses automatically and both get the ip address reserved for them. I have looked over ever other applicable post and attempted the fixes found there to no avail as well. I feel like I am just overlooking a subtle problem. Any ideas to fix the issue?
Oh, at one point I thought it might have been destructive interference from neighboring wireless routers. KisMAC confirmed that there were multiple networks in the area on static channels(4,6,8,9, and 11) with signal strengths high enough to potentially cause a problem. I switch the router to a static channel(channel 1) not being used by the other networks. No change.
