You need to verify the WEP keys.
You cannot verify the WEP keys. The keys are encrypted after you enter
them and are never displayed again. You may need to reconfigure your
access points and end devices to reset the WEP keys.
You cannot establish an IP tunnel to a access point on a remote
subnet.
1. Select TCP/IP Settings and verify that the IP Router (Gateway)
address is correct.
2. Select Spanning Tree Settings and verify that the access points on
both ends of the tunnel have the same LAN ID.
3. Select IP Addresses from the IP Tunnels menu to verify that the IP
address of the remote access point appears in the IP Addresses list.
The throughput seems slow.
❑ Verify that your antennas are well placed and that they are not
blocked by metal or other obstacles.
❑ You may want to add a second access point and implement
roaming if you move the antenna closer to the device and
throughput increases.
You may be able to set filters to eliminate Ethernet traffic on the wireless
side of the network.
