Problem: Wireless Laptop cannot see Wired Desktop on Home Network
LockedI have a wired desktop PC (HP dx2480) running XP SP3 connected to a LinkSys Wireless 4-port router, and a laptop (Lenovo X61) running XP SP3 connected wireless to the same home network (192.168.0.x). The LinkSys connects by cable to a DSL router for internet access. Both PC and laptop get DHCP IPs from the Linksys (which I have hard-coded – mapped MAC to IP). They are on the same Windows Workgroup “HOME”. Both Desktop and Laptop have same Windows User Logins.
My desktop had a virus attack (trojan), which I removed and re-installed XP SP3 (from HP disks). Since then the PC seems to have “network sharing and discovery issues” on the network.
Read a lot of tech-blogs but can’t seem to figure out the problem. I’ll add some more details on problems, and things I have tried.
– The wired PC CAN ping the laptop, but laptop CANNOT ping PC.
– Both laptop and PC CAN access the internet.
– The laptop and PC COULD NOT see each other on Windows Workgroup, or see shares. This got resolved once I added IPX/SPX/NetBios Protocol on both the wired and wireless NICs on both PC/laptop respectively. NOTE: Before adding this protocol, I double-checked that File-Printer Sharing was enabled on both NICs, Windows Firewall had File-Print Sharing as exclusion. I tried everything including disabling firewall on both, disabling McAfee scanning on both, disabling Firewall on Linksys, but nothing worked.
– The laptop CAN see the NAS (Seagate GoFlexHome – connected by cable to LinkSys) using Seagate Dashboard software and direct IP. The PC CANNOT access the NAS using the Dashboard software but CAN access through direct IP. The NAS is named “goflex_home”, which both can discover as \\goflex_home\ from explorer.
– The laptop CAN see ITunes Home Share from a NAS, but the PC CANNOT see any home shares on the NAS (or from the laptop). I even added Home Sharing TCP/UDP ports as exceptions on the Firewall on the PC, but it still doesn’t work.
– Some blog checking the node type on IP addresses given by DHCP. The laptop has Node Type “Hybrid”, and the PC has “Unknown”. I even went to PC regedit.exe and modified theand Change EnableProxy to 0 or 1 (instead of 2 that was in the PC as default).
– I have used SG TCPOptimizer on both laptop and PC to revert to Windows defaultAny ideas? Thanks much in advance.
