The Bad

The ZyXEL P310 does have one bad side though, and it's not even really the fault
of the router itself. Generally speaking, the more you make a tool customizable, the less intuitive that tool becomes. In this case, the router doesn't really come pre-configured with very much, just a few basic filters in the firewall, and the manual is not as helpful as it might be. It's not that the manual is skimpy. At a length of 48 pages, it's a pretty decently sized manual. What the manual doesn't do though, is take you step by step through how to set things up. At all. It just basically tells you what the hardware is, what the various functions do, and from there on out, you're pretty much on your own. This can be a stumbling block if you aren't comfortable with exploring the router.

In my case, I have a very basic setup, consisting of one machine connected to the router, and I use the hardware authentication described earlier. In order for me to get my setup working, it was necessary to:

A) Unplug the cable modem power,
B) Physically plug into the router via crossover cable from my NIC card,
C) Plug the WAN port straight through cable into the Cable modem,
D) Physically connect to the router via serial interface,
E) Program the router for DHCP and MAC address bridging and give it the appropriate DNS numbers,
F) Configure my computer for DHCP through the router,
G) Restart the router,
H) Restart my computer,
I) Go back and tell the router what my new address was in order for it to get the MAC address,
J) Restart the router again,
K) Give it a moment to boot up and grab the correct address for MAC bridging
L) And finally, plug the cable modem power back in.

Wait for it to all sync up, and voile', I'm back in business.

It seems pretty straightforward, except that NO WHERE in the manual does it spell these steps out. You have to figure out not only the correct programming for your type of connection, but also the proper sequence of events to get it running correctly. This can be a huge drawback if you're not comfortable with experimenting and spending some time troubleshooting trying to find the correct path and sequence of events.

You can avoid some of this, by doing pre-installation research and talking to your cable or xDSL company to see what kinds of settings you will need. This is not an intuitive setup though and trying to feel your way through will make for a very frustrating experience.

Configuration Software

I finally got the windows software loaded after I had upgraded the firmware for the router to the latest version, and downloaded the latest software. It's important to note that once you upgrade the router firmware, any configuration you may have is wiped out, so you'll need to write down all the settings you had and reconfigure the router. The windows software is nice looking graphically, but is rather basic, and really only covers simple setup and monitoring. Any real customizing currently has to be done through the serial interface. I sincerely hope they add the ability to configure the firewalls and other services through a graphic interface as soon as
possible, both for convenience, and because the serial interface is a rather dry technical interface, and can be intimidating to novice users.

Support Issues

ZyXEL tech support is decent, usually responding to emails the same or next business day. It took some searching through their support area, but I did finally find some sample firewall configurations to look at, and that made it easier to understand how the firewall setup occurs in the ZyXEL. I really wish they'd included this with the printed manual, and would really push for them to add it to any future releases of that manual. Without those kinds of instructions at hand, and information from your service provider about the type of connection and authentication they do, router setup can be a daunting task.

I cannot really speak to speeds across the WAN port, primarily because I have a 1.5mbps cable connection so I'll never reach 10mbps or anything near it. I've not seen any noticeable slowdown in downloads or uploads as a result of the router now being between me and the my cable connection, and various bandwidth speed tests did not seem to suffer at all, so I feel confident I'm reaching at least 1.5mbps across the WAN. As to latency, the router seems to add between a 5-10ms delay, which is very little for the amount of work it's doing, and worth the extra security it adds.
