Well, while we're waiting for Telskum to give us an answer as to the direction we take with our Internet requirements, I am trying to set up an alternative solution to the MTN router we have in place - it's very basic and doesn't allow much in the way of access restrictions, etc. Given that the minions feel that watching YouTube videos, FaceBricking, and Twatting during working hours (even after having been told we're on 3G and can they please not do it), I need to block their access to these sites.
The D-Link DSL-2750U router that we bought to replace our the blown Linksys WAG320N supports 3G dongles, but is also severely lacking in the access restrictions department (short of blocking everyone). I can use the Linksys E3000 to set up proper access restrictions using MAC addresses, IP's, etc, so the idea was to connect everyone to the E3000 and just use the D-Link as the gateway. I was super chuffed when I connected to the Internet using the D-Link and the dongle, and had gotten to setting up restrictions on the Linksys when we had our first power failure.
Two power failures later, and the frikkin D-Link decides not to recognize the 3G dongle, brilliant, yet it still works when I plug it directly into my PC.
