need help with wireless network

[nexus9]

Greetings. I just set up a wireless network with a netgear MA401 pcmcia card (laptop) and a netgear ME102 network access point. The laptop can ping my server and get to the internet. My problem is that my server can not ping back to the laptop.

The laptop is 192.168.1.101 and the server is 192.168.1.1. Server has arp table entries for both the laptop and the wireless gateway (192.168.1.100) IE:

arp -a
Net to Media Table
Device IP Address Mask Flags Phys Addr
------ -------------------- --------------- ----- ---------------
le1 laptop-wireless 255.255.255.255 00:30:ab:05:f9:52
le1 wireless-gw 255.255.255.255 00:30:ab:07:b0:31

additionally, I can telnet from the laptop to the server. If I add a route on the server back to the laptop via the gateway, I can ping the laptop from the server, but I can _NOT_ telnet/ping from the laptop to the server.

I can't find any obvious routing setting on the wireless gateway... any ideas?

Since they're all on the same network, gateway settings and routes shouldn't have any effect on the communication of the two computers (UNLESS you have messed up on a subnet mask somewhere).

If you are (or were) running any firewall software, check it to make sure the new machine (if you change a NIC, all the other computers on the network thinks you are a "new guy&quot is set to allow the new computer.

That's about it, it's almost certainly NOT a bridging problem at the access point, it's almost certainly something on the server box. Check it out.

Good Luck

Thanks. Neither box is running any firewall software...

I would think the wireless gateway would either have routing settings (there aren't, as far as I can tell) or it should be doing proxy arp.

It looks like the access point is forwarding the laptop's MAC address, which is shouldn't be doing; if it WAS doing proxy arp, it should forward the laptop's IP address with the access point's MAC, right? And if it's supposed to behave as a router, there wouldn't be ANY mac address for the laptop in the server's ARP cache.
