Yeah, I have access points that didn't have the SNMP template applied correctly, they will be lighthttp or whatever you mentioned - so what I did was selected all of them in the assets page, did a mass edit, marked them as access points, until I got the network team to fix their SNMP for them. Then I rescanned them and they updated accordingly.
The way I figured that out, is on the page for the asset, I click the action (I get them confused - there are two actions - test connection and device tester I think - which I personally think they need to rename)... and then I put in the SNMP string and test... I got 'SNMP disabled or wrong community'
In my case, I knew that all the devices weren't locked down to only certain subnets or IP addresses to allow SNMP, so I tested from my laptop... however, the best thing to do is to pull up the program from the lansweeper server and test, because that's what's going to be doing the SNMP connections.
Hope that helps
