I have a 5 PC network, with 1 PC 150m from the hub, which is struggling to keep connection. I know the recommended limit is 100m, so is this a real limit? and if so is there a "booster" device to break it into 2 x 75 metres?
Re wireless yes but 3 issues - speed which is the killer; reliability and security also a problem (wireless would be within yards of public access) but also near RAF station so emmissions may interfere??)
If you can get Category6 cable, it has a specified max length of 200m - one guy says he's tested it on a full 1000m reel OK.
Also thin co-ax - 10-baseT has a 200m length - you could use this for the one outstation, if you get a hub with a co-ax connector (I've done this configuration, tho' only over a shorter distance - 4 on cat5 - 1 more on co-ax.
