My DGL-4500 is sitting on the sideline now, not even connected any more because of the problems with it.
I recently ordered a NetGear WNDR3700 router which came in on the 9th. Since I hooked the 3700 up and configured it, the difference has been dramatically significant.
ISP: Verizon DSL 3.0 MB
With the DGL-4500, it was a struggle to get my Sony Bravia iLink to work and even then, it wasn't worth using. With the WNDR3700, the iLink performs flawlessly and I can use it to watch movies with no interruptions.
When browsing the internet on my system, pages load significantly faster than they did with the DGL-4500.
The DGL-4500 would always present connection problems with my daughter's system no matter what I tried. With the WNDR3700 there are no connection problems with her system on my network.
Altogether, I'd say the experience with the DGL-4500 has not been very good at all and has been a wasted investment.
On the other hand though, the NetGear WNDR3700 has been a worth while investment.
