netgear wireless laptop no ping to/from wired pcs

[bigflavor]

this is enraging me.


okay... i've seen this problem around, with no working solution.

here's the deal:

laptop: wireless, no firewall, xp pro sp2, getting ip from router, getting out to internet; UNABLE TO PING (or any communication with) THE WIRED PCs

PCs: wired, no firewall, xp pro sp2, getting ip from router, can ping other wired pc, getting out to internet; UNABLED TO PING (or any communication with) THE WIRELESS PC.


i have absolutely no idea what is wrong here.

They're all on the same network (obviously); all getting IPs; all can access the router/internet. I can't imagine that there's some firewall setting on the router stopping the wireless computer from access the rest of the lan.

Please, help me.


thanks,
matt

It's got to be the wireless security. Give us more details about that.
btw:
What do you mean that you've seen this around?

BTW:
Welcome to WinDrivers forums.

By "seen this around" I meant just others on the internet.

There is no wireless security (can't get wep to work, which isn't suprising with win xp i've heard).
That's not really a problem for me; i'll take the risk.
but...

I have no security on the laptop (no firewall, windows, software, or otherwise). The only security I have on the router for the wireless laptop is I've limited the access to "trusted PCs," and put in the laptop's wireless nic's MAC.

I never realized that I should probably test the laptop with wired; but of course this will work; because it's a different nic and computers love to mock me. I also know that I have the shares setup right.

The real issue is that I can't ping; I'll get that done, then I'll worry about the rest.


Thanks for the help. I'm glad to be here.


Peace,
Matt

Can you give us the specific model of router and of the Wireless NIC?

[bigflavor]

router: netgear FM144p
wNIC: Lucent/Orinoco "wireless LAN mini PC Card" (that's the name, seriously)

I've updated the drivers for the nic, haven't flashed the router.... maybe I should check that out(?)

Honestly, it sounds like Windows Firewall is enabled (it's enabled by default in SP2) on the laptop.

As far as I know, each NIC has its own firewall settings, so you may have disabled the firewall for the build-in/wired NIC, but not the Wireless NIC.

Check the host file?

Most likely located: C:\WINNT\system32\drivers\etc then the file named "hosts" which you can open using notepad (or other text editor).

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost

You could also try and uninstall/reinstall TCP/IP (and any other protocols you may have installed). Also, for Clients, make sure you only have "Client for Microsoft Networks" as well as "File and Print Sharing" installed too.

That's all you need (or should need). You could try uninstalling/reinstalling the NIC's too. If they're PCI NICs, try putting them in a different slot.

Good luck!
