Works well with Nokia 3650 when lastest drivers used
I purchased the 3Com Bluetooth USB Adapter to connect my Nokia 3650 to my Dell Inspiron 3500 Notebook (running Windows 2000 Professional). Using the version of Nokia PC Suite which came with the 3650 I could not connect. However, once I downloaded the lastest version of PC Suite (version 3.0 18-Nov-2003) from Nokia, and the latest 3Com drivers (bub1_2_10en.exe 30-Apr-2003) everything worked.
The 3Com bluetooth software works with no tweaking, and has a good manual and FAQ installed on the laptop.

Good Adapter, Excellent Software
First, let me say that I'm writing this review with significant experience with other adapters. I work with a lot of Bluetooth technology, and I've made it a point to try different companies' adapters. Most Bluetooth USB adapters are based on the same two chipsets, so the software, form-factor, and range are the biggest issues most users will need to look at. The 3Com adapter is a good adapter, with the most intuitive software I've seen yet. This means that most users not experience with Bluetooth technology will have an easier time using it. Believe me; Bluetooth is not always easy to get working (as a previous reviewer stated). However, do your homework to make sure your device is compatible before you buy it...
Regarding the form factor, it could be a little smaller, and the blinking blue LED is VERY bright! However the adapter wins on the "cool factor" having a blue light-conducting strip across the adapter. Range is average for this class of adapter at 10m (33ft.). I hope this helps!

Not compatible with Nokia 3650
I bought the 3com USB Bluetooth adapter to syncronize my desktop calendar and contacts with my Nokia 3650. The adapter is not compatible with Nokia PC suite which is necessary to be able to synchronize calendar and contacts. I would not recommend it. ... Read more

Buy this modem to avoid renting one from the ISP
I was very pleased to obtain this modem (3CR29210) and installed it without any problems. I transferred the cables from the previously installed modem and the new modem picked up the cable connection in less than 5 minutes.

The only negative is that the package had a sticker on the outside that indicated a different model (3CR29220)should be used for installation on the ( @home ) cable setup.

I called the 3Com installation number, listed in the "getting started guide" and a very capable person informed me that for home use the models were interchangable. That turned out to be the case and I highly recommend this as a replacement for an ISP supplied rental modem. The manufacturer also has a 5 year support warranty for this modem.

Worked right out of the box
This was one of the best deals I had lately. The 3Com OfficeConnect Cable Modem worked right away after I switched it on. No software installation was needed. I was using a Surfboard 4100 from ATTBI in Chicago far north suburb (Palatine). It took about 5 minutes for the modem to sync. The internet connection was up right after that. However, I had to call ATTBI product support to register the new cable modem with them. Otherwise, it would not work anymore after a few hours - I suppose ATTBI has a timelimit set for a new modem to register. The registration was down on a special web page: http://sas.r5.attbi.com. It requires your ATTBI account number and a certain registration number (more like a password). Best is to get a ATTBI tech support person online with you. The styling of the 3Com cable modem is not impressive. I wish it had the Standby button as on the Surfboard 4100. Overall, it worked right away and no hussle.

Great performance on AT&T Broadband (RoadRunner)
After five minutes, I was up and running on AT&T Broadband formerly MediaOne's RoadRunner service (i.e. mediaone.net). Like prior reviews have stated, this modem is 3Com's 3CR29210. Throughout the documentation, you are told to use the settings for the 3Com 3CR29220. This modem offers simple setup and excellent performance.

I was leasing a 3Com 3CR29220 from AT&T and (...) this modem makes financial sense if you plan to use the service for a year or more. It is too bad 3Com couldn't stay in the retail cable modem business and continue to offer inexpensive modems.

good product
At the beginning, I got the same time-out(20 minutes) problem, after calling AT&T many times(more than 10), they realized this is because I had not registered the cable modem with their server. After I registered it with their server, time-out issue is gone. There is a tech who visited my apartment to install the system for me. I just wonder this should be the very first step, how come it looks none of AT&T's support knows it?

Firmware Problems...
3COM cable modems apparently have firmware problems that cause the connection to your cable provider to time-out, so you get a tempermental connection and have to try a bunch of resets to get it going again. My cable provider sadi that as long as it was DOCSIS compatible, it shouldn't be a problem - now I know why not a single 3COM was listed as "supported / approved" on their website (for anyone who cares - I'm with Cox Cable in Northern Virginia).

Get something else that'll actually work. Sure wish I'd known better... ... Read more

Not worth the bother
When I first tried this item, it seemed okay. It came with a decent monitor applet, and the web interface worked okay. The administration was a bit cumbersome, as another review has mentioned, especially with the MAC addressing and general data input. But generally it was a speedy setup.

However, several problems started to pop up. I was never able to get WPA encryption to work. It was just not available at all, unless you use a RADIUS server, something our small business doesn't have. The box clearly advertised WPA as an option, but had a tiny little footnote on the side of the box that stated "available upon ratification" (which took place quite a while ago, from what I understand). So, we have some bait-and-switch going on here.

Next, the administration interface to the unit simply quit after about an hour's use. It would still work as an access point, but I couldn't get in no matter what I did. Yes, all passwords, MAC addresses, IP addresses, and WEP keys were all okay, but the web administration just would not work. I tried several times to hardware reset the unit (something which had worked earlier), but to no avail. It was locked out from every computer I tried it with. The unit went back to factory defaults, and would work as an open access point, but neither the default nor the reassigned IP address would get me into the web administration.

The final straw came when I tried calling the tech support number, which was on the box, the documentation and the web site. The line was disconnected. It wouldn't connect from any phone, including my cell. Repeated emails to tech support from their web site were not answered within three days. I finally gave up and returned it.

So avoid this product, there are plenty of other units out there for less that will perform better than this. USR has a long way to go before this one is ready for prime-time.

Unmanageable
I'm a network engineer for a small business in Northern Virginia. We have about 40 users who connect to our wireless access points. We are expanding to a new floor on our building and purchased 4 x USR5450's for additional wireless coverage.

While the USR5450 may be adequate for a home networking solution, it was an unmanageable solution for our business. In addition to using WEP encryption, we use MAC address filtering for security purposes. It would have been nice to have been able to import a list of authorized MAC addresses without having to enter each individually by hand. It would also have been nice to have had more than 8 characters to use for the name/description of each MAC address. But these oversights are forgiveable.

Compounding the problem was the fact that the web interface wouldn't even allow me to cut and paste a MAC address, but required a tab between each pair of hex digits. In addition, for each address I added, the web interface would forward me to a new web page telling me that the system was resetting. After waiting several seconds, I could click on the "Back" link and enter my next MAC address. In frustration, I turned to the US Robotics supplied software.

Before continuing, however, I thought it best to update the firmware to the latest version. Perhaps a newer version would fix some of the glaring problems with the interface. I noticed that the new firmware was supposed to allow 64 MAC addresses. I hadn't seen anything previously about this limitation, but began to worry about running out of MAC addresses. I wondered what it had been prior to the firmware upgrade. I downloaded the new firmare and installed it--only to find that it totally wiped out all the MAC addresses I'd managed to input along with all the other configuration changes I'd made. Unbelievable!

So I downloaded the latest configuration software and gave it a try. I was pleased to see that I could cut and paste MAC addresses individually and that the system didn't reset after each one. However, the configuration software didn't let me enter any sort of name or description for the MAC address. (I would soon learn why.) In any case, the interface was still incredibly clunky, requiring me to hit the "refresh" button after each "apply" before I could make any additional configuration changes.

I loaded the entire list of MAC addresses and then opened the web interface to see if I could add a name/description there. To my surprise, I noticed that several name fields were already filled in with junk binary characters. I cleaned them out. However, when I then looked back at the configuration software, I noticed that several of the MAC addresses I'd entered had disappeared. It took me a few times of adding MAC addresses and deleting junk characters before I realized that the config software must be using the name/description space in order to store additional MAC addresses. Disgusted, I told my manager that I thought we should send back the USR5450's and try a different product and vendor.

I can't really comment on how well the hardware works, which is why I'm not giving this review lower than 2 stars. But for me, the software and web interface were enough to convince me that this product wasn't for me. It was just too unmanageable.
