MrNewName 18:37 08 Jul 2011 Locked I'd like to put an internet access point in a place which will require about 200 metres of cable and before I invest in that amount of cable, I'd like to know if it is actually possible! The Router/Modem is fairly new (although I can't recall make/model at present) but would it need to be upgraded? The ISP is BTConnect; currently works great both cabled and wi-fi. Will 200 metres of cable degrade the speed? Thanks for any advice. mgmcc 22:19 08 Jul 2011 Maximum length of ethernet cable run is generally 100 metres for Cat5/Cat6. MrNewName 08:28 09 Jul 2011 Thanks; that answers that question. Cheers. Forum Editor 22:38 13 Jul 2011 "Will 200 metres of cable degrade the speed?" In a word, yes. If you want to install a run longer than 100 metres you'll need to introduce a repeater at the halfway point. MrNewName 07:55 14 Jul 2011 Thanks, that's an option I'd not known about. I'll be sorting this out in a month or so. onthelimit1 11:37 14 Jul 2011 An alternative, if the locations are on the same mains circuit, is the use a pair of Powerline Homeplugs here This thread is now locked and can not be replied to.
