I have it working with 128bit WEP encryption. I have (3) access points all together (including the router) and I can roam pretty well with the NevoSL. The only thing I noticed is that when doing the wifi setup on the Nevo, I needed to have the key/encryption type to Open, not shared or anything else. When I did this, my strength went from very low to very good/excellent. Working pretty good so far.
