I am using a Linksys WRT54GS wireless router to provide internet connection for a desktop and a laptop at home. The desktop is hooked up to the router directly (i.e. wired), while the laptop is connected via wireless. The desktop runs XP Home SP1, while the desktop runs XP Pro SP2. Both can connect to the internet without problem.
The only problem is, they cannot ping through each other. Both are configured to use the same workgroup, using the same gateway192.168.2.1 (which is the IP of the router), and using the same netmask 255.255.255.0. The desktop has IP 192.168.2.100 and the laptop 192.168.2.101. Both are installed with (a) Client for Microsoft Network, and (b) File and Printer Sharing for Microsift Network.
After additional config to the router via IE (by creating two routes "desktop" and "laptop" with their corresponding IP addresses), I can now ping from desktop to laptop, but still cannnot ping from laptop to desktop. The later is what I want, since I want to share the printer from my desktop, and be able to access the shared printer on my laptop.
Would it be the problem of the router hardware, or router configuration, or my Windows configurations?
Any help appreciated.
