I'm still using the original Westell 327W with 4.04 firmware. The connection is a pretty solid ADSL2 at 1786/443. The new Netgear(Westell) 7550 Frontier sent syncs at the same rate, but says I only have 6.1 dB download margin whereas the Westell 327W says 21.5 dB.Plus the new Netgear reboots a few times an hour, so I kept the 327W.I'm not sure if the Westell is being overly optimistic about the SNR, or it's just a crap 7550 that.he new Netgear(Westell) 7550 Frontier sent syncs at the same rate, but says I only have 6.1 dB download margin whereas the Westell 327W says 21.5 dB.

The best topology is ring topology. Star is the next best after ringr, and then bus, which is pretty old, but not too expensive. Full mesh topology is theoretically the best since every device is. connected to every other device, thus maximizing speed and security. These, however, are quite expensive to install. The next best would be. tree topology, which is basically a connection of stars.
