3Com OfficeConnect Dual Speed Hub 5 - hub - 4 ports

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 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
