Apparently, some had heat issues. Also, better on 22V DC rather than older A/C bricks. Funny, the unit can take either. http://www.dslreports.com/forum/r27178966-SpeedTouch-516-Overheating-problems-

D-Link DSL-520B

Some rough notes on change to bridge mode in Telus land.

- http://swisscobalt.blogspot.ca/2009/01/how-to-bridge-dsl-520b-with-wrt-54gc.html

- comes in modem+router mode.

- 1 ethernet port in back

- admin page http://192.168.1.1. Default username/password is : admin/admin

- Advanced Setup > WAN > Add

-- Hmm... bridge term is used for multiple things... bridge ATM to ethernet, and bridge LAN to WAN vs router.

- [next] Connection type : Bridging - Encapsulation Mode : LLC/SNAP-BRIDGING

-- disable DHCP (not in post, in comments)

Better... specific to Telus land

- If you wish, instead of the setup cd, go to 192.168.1.1 and login to the device with the id and password admin/admin.

- Go to advanced settings.

- WAN - UBR 0 33 (Not 35)

- LAN - Turn DHCP off

- Save settings.
