I do not know which Office Connect Router exactly you are currently using (as 3Com has several devices with this "selling name", the exact designator would help me a lot, the device should have a product number starting with 3C....) but please check the 3com website if you have the most recent version on your device installed, 3com had some issues with these special characters in older firmware releases and they can be resolved in mostly all cases with the upgrade to the latest firmware.
