Today I installed DD-WRT on my fathers Buffalo router. All seemed well however we’ve discovered a networking issue I could use your help with. If you know Windows, DD-WRT and or networking please read on. If not, boring geekiness you wont care about below the break.
My father has three machines. We’ll only refer to them by their IP addresses. 192.168.1.2, 192.168.1.3 and 192.168.1.4. These machines used to all speak to each other for file and printer sharing just fine. However now that we installed DD-WRT they are not communicating properly at all.
Each machine can browse the network and see the other ones but can not connect to one another well. 192.168.1.3 can connect to 192.168.1.2 but not 192.168.1.4. 2 and 4 can not connect to anything. This is via both the Network Browser and run:\\192.168.1.x.
Is there a setting in DD-WRT that could be blocking this? Is there something I need to do in Windows? I’ve already run the “Create a new network” wizard multiple times. They are all on the same subnet of 225.225.225.0 and the router is on that subnet too. No settings have been modified on the router other than the timezone and wireless setup; however none of these machiens are even wireless!
I could really use some help on this as I feel that I’ve left my father with an unusable computer setup.
Update: It appears to have been a firewall / Internet Security Suite issue as changing the IP addresses to the same range the old router used, 192.168.11.* all seems well. Now the issue is wireless! Both of his devices, Windows PocketPC 2000 and an old Linksys Wireless B card seem to not have the required security reqs for the router. I am of course not there so going on word of my father. Hopefully he can get this resolved with updated drivers or something.
