I recently began having a problem getting my Quicksilver G4 (OS 10.4.9) using 802.11b to "see" anything else running on my LAN. It had been working fine for the last 3-4 years.
Here is the background
- A mixed LAN (802.11b wifi, 100MB wired ethernet, and Homeplug).
- Two networked printers (wired ethernet)
- Two WinXP machines (one wired, one 802.11b wifi)
- Two SUSE Linux machines (both Homeplug).
In February, I upgraded the G4 to Tiger... That seems to have been the start of our problems. We seem to have had intermittent problems connecting the G4 to the networked printers ever since (the local USB printer works fine).
Yesterday I shutdown all the machines (computers, routers, printers, etc.) because a line of thunderstorms was coming through. When I started up again, the G4 cannot see anything on the LAN... Here are my attempts at narrowing things down:
- G4 can HTTP to any Internet site I have tried
- G4 cannot HTTP to LAN http servers
- G4 can successfully ping the router (192.168.1.1)
- G4 cannot ping any other IP node on the LAN (e.g. networked printers or other computers on the LAN.
- WinXP machines (wired and wifi) can HTTP to both Internet and LAN http servers
- WinXP machines (wired and wifi) can ping router and all LAN IP nodes
So my G4 can connect to the Internet fine via 802.11b wifi but it cannot connect to
any of my local LAN devices. All my WinXP and Linux machines can connect to
both the Internet and the LAN using wifi, wired ethernet, or Homeplug.
I have seen another post which indicated that some routers allow one to isolate the wifi from the LAN (some sort of toggle setting). But as far as I know my Linksys does not have any such toggle and, in any case, my wifi WinXP notebook would have been isolated from the LAN along with the G4. And the notebook is working fine.
Can anyone tell me what is wrong and suggest a fix?
The G4 worked fine with this configuration for a number of years and I am puzzled as to what is wrong.
TIA,

PS Here is what I get when I try and ping a local LAN connected IP address
ping 192.168.1.200
PING 192.168.1.200 (192.168.1.200): 56 data bytes
ping: sendto: No route to host
ping: sendto: Host is down
ping: sendto: Host is down
ping: sendto: Host is down
ping: sendto: Host is down
ping: sendto: Host is down
ping: sendto: Host is down

If I try the same ping on my WIFI-connected WinXP notebook, I get good ping results.
