Hello everyone, I'm fairly good with comptuers / networking but this issue has me baffled. Help would be greatly appreciated. I have a linksys router (WRK54G) and have 2 desktops and 2 laptops connected to it wirelessly at the moment. I bought 3 smart phones and a new laptop recently. I don't use encryption but I do have MAC address filtering enabled. The issue is that 1 of the smart phones can connect to the network and the internet, but the other 2 phones and the laptop can connect to the network but not the internet. I did add their MAC addresses to the "allow" list ofcourse, which is why they're able to connect to the internet. DHCP is enabled, and these devices get an IP address. I can see them as connected when i log in to my router as well through one of my other computers (I see the MAC address and the IP assigned to those devices) so I know they're properly connected to the network. However, when i try to pull up a website (using either its ip or its domain name), the devices try to open up the page but eventually give me a "The page cannot be displayed or downloaded because the connection was lost" on the pocket PCs, and a generic "page cannot be found" on the laptop. I don't see these requests in the outgoing log table of the router either... I'm supposed to see them as when i use one of my desktops, I can see which site was accessed by which IP. So basically, the requests from 2 smart phones and 1 laptop aren't even getting to the router apparently. What could be wrong? These devices can access the internet on other routers elsewhere at my workplace or at wi-fi spots.. just not at home, which is a major inconvenience. Help will be truly appreciated.
