Advantages: Reliable, dual speed compatible, built in management
Disadvantages: Connectors have begun to rust - might cause problems in the future

...Preface = When you work so much technology around you, like I do, you begin to learn which technology is more reliable than others - especially when you have to deal with warranties/replacements! Some hardware is appalling, and without mentioning any brand names in this opinion I would say that the monitors that we use are the most unreliable monitors I have every seem. Seriously, we replace one at least every couple of weeks. But then you get some pieces of hardware, like the 3com Superstack II hub, that you don't even remember exists. It just sits in the corner of my office, doing its job, and just doesn't stop. That is why I'm writing this opinion. This hub deserves recognition for its reliability - as it's a fine piece of kit. The 3com SuperStack II Dual-speed hub 500... Read review

Advantages: Simple, dual speed, small size
Disadvantages: Only 5 ports (?)

...Not much to say about this really. I bought this for a pound (!) on Ebay to connect to my router giving me 4 more ethernet ports to connect stuff to my network. That's all it does, gives you more connection; there's no firewall, DCHP, nothing, but then that's all in my router. Its 5 autosensing ports (Ethernet 10Base-T/100Base-TX - RJ-45)automatically detect the speed of the attached device to maximize network performance - with a data transfer rate of up to 100 Mbps. It really was a "plug-and-play" installation with no configuration needed, it connected straight into my network - I didn't even ned to read the manual ! The auto-sensing feature means that you can plug the "in" cable into any socket - another 3Com switch I have has a specific "in" port. It's nice and small (Weight 0.6 kg, Height 4.2 cm, depth 13.5 cm, Width 22... Read review

Advantages: Quick, Eaxplained configuration, specifications
Disadvantages: A bit costly.

...At £1700 this is not the cheapest firewall you can buy. However, 3COM seem to have the ability to make good quality units with minimal fuss. You certainly get what you pay for with this unit. I already have one of these at work and have recently purchased another for an additional office. First and fore most the Superstack 3 has a good quality durable rack mountable design. Ports and LEDS on the front are clear and readable so there is no confusion in an other wise confusing technical world. The rack mounting kit is actually included with the purchase. The S3 is managed via a WEB based interface. Connecting at first is easy with a quick read of the manual. The WEB interface is as you would expect, clear understandable and split up in to logical sections. Logging in comes via simple login and password. You get a general summary page... Read review

Advantages: Ebay bargain !
Disadvantages: Only 10 mbps, Only 4 ports

...Bought this on Ebay for a bargain £1 to expand my network. I've since replaced it with another 3Com hub (check out my other reviews), but thought I'd still let you know a little about it. It's an entry-level, 4 port hub, but only 10BASE-T, rather than the faster 100BASE-TX - that's why I upgraded, so you can connect 4 users together. There's one (manually switched) MDI-MDIX port to provide simple "in" connection from a server, switch, or hub, and three other female RJ-45 ports to send the network signal out to 3 other items. The hub has an external power supply and a "CoolCurve" self-cooling design eliminating the need for a noisy fan. Its dimensions (height: 3.6cm, width: 23.1cm, depth: 13.6cm) allow it to fit nicely with other 3Com OfficeConnect units - special stacking clips are available. It's an "unmanaged" hub, so...
