Cisco 1800 dot11radio0
I have an 1800 cisco router with a wireless antenna that randomly drops at least once a week and stays down for a random duration. USually around a several hours, then comes back up.
If I do a "sh ip int brie" it shows my dot11radio0 as being "reset". I have never seen an interface actually stuck in a "reset" mode. Usually when you do "sh ip int brie" the interface is either up or down.
Any clue as to why this client wont auto reconnect back to the AP router? Here is the config on the interface.
IIS-R0#sh run int dot11radio0 Building configuration...
Current configuration : 259 bytes ! interface Dot11Radio0 ip address 192.168.254.2 255.255.255.252 ! encryption mode ciphers tkip ! ssid SSI ! speed basic-1.0 2.0 5.5 6.0 9.0 11.0 12.0 18.0 24.0 36.0 48.0 54.0 station-role non-root antenna receive right antenna transmit right end
One other thing that really confuses me is the use of a "Virtual- dot11radio0" interface which seems to be completely nonprogrammable from the CLI. What is this virtual interface and why is it even being used? If I have to use it why cant I program it from the CLI? I always found the SDM to be awfully limiting.
sh ip int brie shows Dot11Radio0 192.168.254.2 YES NVRAM up up Dot11Radio1 unassigned YES manual administratively down down Virtual-Dot11Radio0 192.168.254.2 YES TFTP up up
Any help would be truely appreciated!
