All, I solved a very similar problem on my network last night: Linksys WRT54GRouter V1.0 3 XP Pro Machines 1 Win 7 machine All were working, pinging andsharing fine until I replaced the router with a WRT54G V8.0. After that, I couldonly ping some machines from some others, and could not share any drives orprinters. I was positive this had to be a router problem, but it turns out it was aweird McAfee firewall issue (probably something to do with how McAfee relatesto the routers MAC address). The solution that worked for me was as follows:The range of trusted networks in the McAfee Firewall settings was correct(192.168.1.1 > 192.168.1.255). However, after trying everything else I couldthink of, I deleted the rule that allowed this trusted range within the McAfeeFirewall settings. I then recreated it exactly as it was, and Voila! I could nowping that computer from every other computer. I did the same on all machinesand the problem was solved. I hope this helps someone.

ANSWER

bobd Jan 10, 2010 01:23PMThanks; this worked for me too. There were conflicting entries for the IP range I use, some Trustedand some Public. I suspect a bug in the McAfee update as it had happened to several PCs. One of them was totallymessed up, with hundreds of bizarre ranges. It's going to take an age to remove them all.

I had the same problem, with my US Robotics router 4 years ago and forgot howI resolved the problem. Had the same problem with my new Linksys router. It is not the router, it is your computer firewall. I use Norton and you need toconfigure the firewall networking trusted addresses. Enter the non routeable IPrange that your wireless network is using e.g. 192.168.1.100 to say192.168.1.110. I do not use Windows Firewall, but I presume it has similarsettings. I am now able to share files and printer again. Next time I buy a routerI will have probably forgotten all this and will have to go through the samelearning curve again. Richard

Check to see if the option AP isolation is checked in the advanced Wirelesssettings of your Linksys router. Are all the computers wireless ? Is so this couldbe the issue.

ANSWER

QuantaCat Feb 27, 2009 11:09AMSims: Wireless | Advanced Wireless Settings | AP Isolation was off on my router at home where it isworking and on this router where it is not working. However, under Security | Firewall, BlockAnonymous Internet Requests was not checked at home but checked on this other router. Iunchecked it and now some of the PCs list the others in the Network list. The one with the printer,however, does not have the others listed and the others still can't access that shared printer. So, Ihave more work to do, though we did make some progress. Thanks, Rob

QuantaCat Mar 13, 2009 07:26AM

Update: Apparently this change did it unblocked anonymous Internet request on my router.Apparently it took a little time, perhaps system reboots, whatever, for it to take effect. All the PCscan print to the shared printer now all see all PCs, etc., etc. Thanks to all for your suggestions! Rob

Similar issue, different problem. I just hooked up a Linksys wireless router to a two printer, two XP LAN network.Previously, a Linksys wired router was the hub and worked perfectly fine. This isthe second wireless router brand I've tried with the exact same results. Thenetwork shares the printers and some shared software/files from the hostcomputer. This is not a home network, only mapped drives to software andshared printers. All are wired (plan on hooking in with a wireless laptop once thisissue is fixed). Both computers can ping the printers and router. Computer A(host) can ping comp. B (client). However, computer B cannot ping A. Windowsfirewalls are off on both computers. The IP address are fine and so are thesubnet mask ids. Literally, if I unplug the wireless router and reinstall the wiredrouter, the problem is solved. Any thoughts. I figure it has to be a firewall on Abut can't figure out where. ICMP boxes are checked for incoming echo requestson both. HELP!

In order for your computes to ping each other on a network level, they have tobe on the same network. Go to start menu, rightclick Computer(Vista) or MyComputer(XP) and select Properties. In Vista, change the workgroup name sothey're the same on both computers. In XP, in the properties windows go toComputer Name tab and change workgroup name on both computers. Bothcomputers are no on the same network, but the computer must be restarted forchanges to take effect. Also, if you want to enable printer and file sharing, for XPopen windows explorer (start menu>all programs>accessories>windowsexplorer). In the left window find the C drive and rightclick and choose "sharingand security..." and in the properties window under Sharing tab, click thebottom sentence. In the "Network sharing and security" window, check the"Share this folder on the network" box and then name the folder what you want.If you want, you can allow others on the network to change files by click the"Allow network users to change my files" box...otherwise, leave it unchecked.Click OK and you now have a network sharing folder. Go through the sameprocess on the other computer (if running XP) to enable printer and file sharingon there too. On Vista..well, you'll have to look it up cause I can't remember atthe moment. I use Win7 and the features are slightly different I believe.

ANSWER

QuantaCat Feb 27, 2009 09:13PMThanks, Dark Nuker. On my PC, all those things are done already, except enabling printer sharingon the other computers even though they don't have printers attached. Maybe, by some screwy logic,it's now required by Vista I'll try that. Rob

MAC filtering Reboot PCs these are just some of the things I tried! Then one day, I rememberedchanging the security from WPA to WPA2 just before the house move, although everything'appeared' normal I must have lost the connections between PCs at that time and not discovered it. Ichanged the security back to WPA and hey presto, all PCs could talk to each other again. Hope itworks.....I know its frustrating.

some of the addresses. All have Network Discovery enabled. One has a printerit's sharing without a password. LLTD is enabled on all wireless (PCI) networkadapaters. I uninstalled Norton Protection Center that came with, and replaced itwith just Norton Antivirus. All Vista firewalls are disabled and there is no otherfirewall software that I know of. All are part of the same workgroup and on thesame network. When I look at the Network Map for all PCs, they have only theone host, the network and the Internet nothing else. What gives? At home, I have 3 XP PCs and a Vista PC all talking together, sharing, etc. nicelywithout a single hiccup. What gives with these jokers? Thanks, Rob

wcruz Feb 16, 2009 04:58PMPut in your computers IP address in the "Trusted" list inyour Firewall Software. In McAfee thetrusted "range" 192.168.1.1 though 192.168.1.255 was there but it wasn't working. I added mylaptops specific address 192.168.1.3 and 192.168.1.4, then they were able to ping eachother and therouter could ping the laptops.

Quantacat Feb 17, 2009 08:31AMWcruz: Thanks, but the only firewall on the system is Vista's, and it's inactive. Before I removedNorton Protection Center, I tried entering the MAC addresses of each machine to no avail. So itseems it's something other than a firewall issue. I have a Linksys wireless router at home that has 3 XP and one Vista system all talking nicelytogether even though the Vista is part of a different workgroup. Thanks for replying, anyhow.
