Cisco 851w and Linksys WPS54G printserver

Recently i bought a Cisco 851W to replace a Linksys router for a customer.

The wireless connection between the router and printserver were fine before i replaced the linksys with a Cisco. But when i implemented the Cisco router things started to go wrong.

The wireless connection with the print server drops multiple times per day and requires a reboot from both the router and printserver to get it back online.

Here's the config that matters on the Cisco 851W:

dot11 ssid *

vlan 1

authentication open

authentication key-management wpa


infrastructure-ssid optional

wpa-psk ascii 0 *


interface Dot11Radio0

no ip address


encryption mode ciphers tkip


encryption vlan 1 mode ciphers tkip


ssid *


speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0

station-role root


interface Dot11Radio0.1

encapsulation dot1Q 1 native

bridge-group 1

bridge-group 1 subscriber-loop-control

bridge-group 1 spanning-disabled

bridge-group 1 block-unknown-source

no bridge-group 1 source-learning

no bridge-group 1 unicast-flooding


interface Vlan1

no ip address

ip virtual-reassembly

bridge-group 1


interface BVI1

ip address

ip nat inside

ip virtual-reassembly

no ip route-cache cef

no ip route-cache

Any help is greatly appreciated.

Thank you in advance!

Since the printserver is 802.1g, try to disable 1.0, 2.0, 5.5 and 11.0 and set the others to basic. You can also try to disable shor preamble on the interface Dot11Radio0.1 no preamble-short.

Maybe also update the printserver to the latest firmware.
