As SD says.
I had so many problems with Belkin stuff that I don't allow it in the house. Ditto both daughters at their homes, and a couple of other folks I know.
It may be better now than it was 4 or so years ago, but I'm not going to take the risk.
Netgear was so-so, I was pretty happy with Linksys, very happy with Draytek, and stunned with Cisco. But setting up the Cisco is a long and tortuous process, not for the faint hearted.
If the line keeps dropping, that may not be the modem's fault. I'm a long way from the exchange, and sometimes I will get a "dropout" every few days. Then it'll go for weeks with nary a hiccup. It may be to do with rain, or something - I don't know. Folks who know a lot about this stuff have looked into it, and say it's just distance and noise levels. Better modem = better results, but it's not going to be perfect.
The Netgear dropped the line about daily, the Belkin about every half hour. YMMV
