4 out of 5 eggsOptions galore

Pros: Great modem if you know a bit about telneting into devices. The out of the box settings tend to be less than optimal and you will sometimes get problematic connections that is if you can get one at all. Do a bit of research though and you can make these into the most dependable modem you've ever had.

Cons: For one the price. I bought 3 of these for 1/10 the current price 4 years ago. 5686d's have some small hardware differences but a firmware update can bring them to exactly the same level of functionality.

Second for those who don't have the patience to figure these out or at least have some experience configuring devices through telnet, this can be a nightmare to configure. If you've been through a hands on Cisco course you should do fine though.

I live in an area so behind the times that we can't even get near a 56k connection. The dial-up servers in my area would reject 3/4 connection attempts and only connect for a few seconds on the others. Until I disabled several of the features on this modem it wouldn't stop trying to force a 56k connection. After that I never had a single dropped connection even with active connections for several days at a time.

Other Thoughts: Now I'm a 3Mbps ADSL user wishing the local telcom would pull their heads out of their behinds long enough to update the lines and stop charging premium prices for worse service but that's another story. This modem lasted me a good 2 1/2 years before they managed to get services other than dial up to my area. It's a disgrace that telcoms and cable companies are still allowed to monopolize certain areas of the country and charge whatever they want for service no matter how bad.

3 out of 5 eggsNot the best

Pros: It provides many indicators and options. The form factor is ok, and its very popular and common making it easy to replace.

Cons: This modem is not the best there is like others claim. It suffers from dropped connection on lines with high noise (db noise) and although claims to support most protocols, its hard to program and get the modem to negotiate a solid link. MultiTech and a few other make a more robust and reliable modem at the same price point.

Other Thoughts: Learn the AT command set to get the most out of it!

5 out of 5 eggsThe Standard.

Pros: The standard by which all other modems are measured. Compatible with everything, and I do mean everything. Hardware-based, full Hayes-compatible (AT type) command set with extensive documentation at USR's website. Standard serial interface. RS-232, not USB.

Cons: Newer ones occasionally fail. I had one of these guys brick up 2 years back. Of course, this was after one of my coworkers - a man of incredible genius - covered the ventilation ports with packing tape, trapping heat inside.

Kind of cheesy they don't include a DB9 to DB25 serial cable with the modem.

Other Thoughts: Many computers these days don't come with a "standard" serial port (RS-232 - not USB) as they've been (somewhat) deprecated. Often the mobo has an unused internal connector for a serial port though, and if it doesn't, expansion cards are purchasable. (Don't use a USB to serial adapter with this, as the emulation isn't perfect.) You need a real RS-232 port to run this baby. You also need a DB25 to DB9 serial cable.

Also, ensure that you get a telephone surge protector and keep the modem ventilation ports clean. If you do this, it will be the last POTS modem you'll ever need.

4 out of 5 eggs

Pros: Works on Linux Debian: just plug it in. If it's your first ever dialup modem install pppconfig and run that to configure it.

Cons: The price is ridiculous of course and you don't get a modem cable with it. You have to get a DB9 Female/DB25 Male Modem Cable from somebody else, because NewEgg don't sell them.

Other Thoughts: I bought this because at the time it was the only serial dialup modem available. The Zooms are less expensive and come with the cable.

4 out of 5 eggsWorks with Allen Bradley PLCs

Pros: I use them with Allen Bradley MicroLogix and SLC PLCs. Beats spending $500 on an AB modem.

Cons: Should be supplied with a DB9 to DB25 cable, especially for the price .

3 out of 5 eggsplease tell people they need serial cable

Pros: I don't have any yet see cons

Cons: I know other modems come with
the cable they need to connect
to the computer this one doesn't
if you have any time constraints
this is not good please newegg
state somewhere (needs rs-232 cable db25 male on one end your
pc's reciprocal connector probably a female db9 at the other) all I needed was a simple line of text.

Other Thoughts: We'll see if you don't get a connector for more money than
all the others cost what else
don't you get

1 out of 5 eggsMuch Aggravation

Pros: 12 years of computing, back to the DOS 6.22 days, yet I can think of nothing, absolutely, unarguably nothing good to say about this USR5686

Cons: None of what I have to say here is related to Newegg. It's not their fault. My mobo, graphics card, stick drive and other HD's all come from Newegg. BUT, I gotta say something nasty about this junker USR 5686 modem, as it has caused me considerable grief. And the unit I bought cost $40 more than what they're charging now because it was a couple years ago. Anyway, all I did was switch to a PCI card plug in modem, and the seemingly limitless headaches disappeared. All the problems I've had exceed the space limitations here so I'll say no more. I'm looking for another modem for a 2nd computer and I'll pick anything in sight, except US Robotics. Big name, tiny dependability. USR website is user UNfriendly; call on phone and get nowhere. Nonstop headaches. No more of USR for me.

Other Thoughts: Fellow Newegg customers, please remember how important it is to UNPLUG your computer gear, and these darned modems, when T'storms come visiting. That includes the phone line from your modem as well. They are VERY EASILY damaged from storm-generated surges. Doesn't take much. And I've constantly protected this modem from storms, so whatever has caused its failure is certainly not related to storm surges, which makes the failure of this unit all the more unsavory.

4 out of 5 eggsGood modem

Pros: Good modem.

Cons: Can only get 28.8k,but think it's the phone lines.(only get 28.8k on several modems before this one)Using with XP PRO X64 the software bundle will not work with X64.Windows driver worked fine,but updated to USR's drivers anyway.

Other Thoughts: If you can't get broadband(like me) and you don't want to use a PCI modem,this is a good one to get.
