Ping (and connection) problem between 2 wireless in Fedora 10
I have a home network with one small server (as Internet router), connected to a cable modem on one side and wireless router Trendnet TEW-425BRP on the other, which is used as AP only.
The devices in the network are as follows:
1. Laptop with BCM4311 wireless card, running Fedora 10.
2. Desktop with RaLink RT2561/RT61 wireless card, running Fedora 10.
3. Nokia n810 with Conexant cx3110x, running latest Maemo.
4. Brother wired MFC with Ethernet adapter, plugged in the router.
5. mini-PC with 2 Ethernet cards running NetBSD and serving as an Internet router/server.
Firewalls on all machines, but the the NetBSD (router of the Internet) are off.
The reason I am listing them all is that is to point the problem. Initially when I try to ping from wireless to wireless (say from 1 to 2 or 2 to 3 or 1 to 3) I get "Host Unreachable", but if I ping from both a wired machine, then they can ping each other. Internet is accessible anywhere in the network -- no problem with that. Only when there was no direct connection between the wireless hosts for a longer time I can not ping from/to another wireless. Especially between the two 2 Fedora 10 machines.
I have checked all configurations and routing tables and they seem fine.
There must be something with the wireless or the set up of the devices (drivers) that I am missing.
What could be the problem?
Thanks in advance!
