When it comes to being the best ADSL modem you will find that most people will agree that it is the Billiom BiPAC 7800N. The modem has one of the fastest throughputs of any ASDL modem. The modem is near the top when it comes to sync speeds. When it comes to stability the 7800N has proven to be the best. If you are looking for a core modem for your ASDL2+ network this is the modem to use.
Another great ASDL modem is the Linksys by Cisco WAG320. It is a well-rounded modem that comes with some great features and software. One thing that is a bit of a disappointing is that it does not use it’s 5GHz to full potential. The modem only comes with a one year warranty compare with the two or three years offered by other companies.
If you are looking for a modem to use for online gaming you will want to take a look at the D-Link DSL-604+. It runs a wireless connection up to 54Mbps. The user interface is more geared towards technical users, but if you want top speed for gaming it does not get faster then this modem. The other positive is that the price is similar to mid-range modems and this is more high end.
