Wireless and security
MattM, Like many others here, I am using my own router plugged into the Optik D-Link 3810 router, and have no problems with that - simply plug your router WAN side to the D-Link. No fussing with static IP addresses was needed. But unlike others who want network connectivity between their wired and wireless devices, I don't trust the wireless security enough, and prefer to keep it separate "outside" my LAN. I compromise and use the D-Link wireless only for Internet access. All my other stuff is wired LAN behind my own router.
By the way, one reason I don't trust the wireless side, is the 3810 only appears to support WPA-PSK and WEP protocols. WPA2-AES (stronger) doesn't seem to be a choice. For sure I would not use WEP and WPA can be cracked too if you are using a weak password. Obviously best to use a strong password. In any case, until TELUS upgrades the router to support stronger encryption, the wireless side stays "outside".
