I did, and I'm currently on a reduced speed connection right now! Thought it was Vodafone's fault, but nope, using the connection straight from the MT882 was perfect.
The whole connection will just break off suddenly for sometimes 2 minutes at a time and start again. The LAN connection to the router does "appear" but logging in to the router fails. But now the outages are getting more frequent and now in 5 minutes of starting it up after a long rest.
Second question: What would be a good replacement for a WRT54G (or even both my MT882 and WRT54G)?
It has to be under $130-ish though (for modem + router)
Looking at a Dynalink RTA1025W... that's quite good apparently.
