Title: Modem Router, cables and what to do?
Post by: neXus on January 28, 2007, 14:12:52 PM
Hey again

Ok, I have had my net issues and there seems to been a surge and took out a point between me and the exchange but it also seems the point to my house needed fixing and a cable I had is now knackered bt engineer said which actually does seem to be true.

Our house phone point is downstairs and normally my router is in my room and cable ran from the phone socket up here.
The cable is dead and I was getting very slow speeds.
Router directly at the phone point and I can get good speeds but there is no power socket for the router there and currently running an extension cable into another room (wok while parents are away but not viable)

I have a net cable leading to this point for when if ever there is power there.

The modem router uses the old power fat plug and lead to jack into the modem router.
Now is there a very long extension cable that I can run to the router from my room to a power socket or is there a very good strong grade broadband ready cable I can run from the phone socket to my room?

THanks

I had a similar problem to this, all of a sudden after over a year of use my internet started dropping and speeds were low. Turned out the normal phone cable I was using as an extension had degraded and was no longer fit to carry ADSL signal.

I bought one of these to fix the problem:

Ebay linky (http://cgi.ebay.co.uk/20M-ADSL-RJ11-Broadband-Cable-Lead-SENT-TODAY_W0QQitemZ270080713858QQihZ017QQcategoryZ67857QQrdZ1QQcmdZViewItem)

Arrived next day and im back up and running.

When doing something similar for a friend I looked in the next room and found that there was a socket on the joining wall, pulled off the skirting board in the room they wanted power, put through a bit of cable from the old socket and wired in a new one.

Really you only need a hole through from the present power socket but it cannot be live while you do it - use a rechargeable drill. You can then put a surface mounted box over the hole and put some cable through.

If you do this then and use 16 amp cable remember this limit for using the socket(s)

I still would not recommend more than 10 meters from phone socket even if special cables you will get a better speed and less proplems having rj45 all the way. Find a way get power to the place or run it from a 12 volt car battery :)

2.5mm cable is 20Amp limit, hence the reasoning for running 30amps on a ring main, you have 10amps of tolerance.  I still wouldnt be inclined to put a double socket on the end of it though, some people are dumb enough to put a kettle and iron right on the end of the only spur socket in the house.

If you have a modern box go and look inside, the cable may be able to withstand 20 amps but the rating is 16, all modern trip switches for ring mains are 32 amps. This rates a single cable at 16 amps and you can get 16 amp rated trips. You cannot easily get 15 or 30 amp rated trip switches.

BTW I have just done some wiring and a new box.

My dad will get power there one day, but for now the cable will do its not more then say 2 meters its straight up from the socket to my room upstairs.

Thay have been 32 and 16 for years, even with the old fashioned Wylex units that Centaur also rip off.  The actual ratings of the cable are:

1mm : 10 amp
1.5 : 15 amp
2.5 : 20 amp
4.0 : 30 amp
6.0 : 40 amp
10.0 : 50 amp

Those are the advised maximums, though the cables themselves will take a more.  Its all down to tolerances on the cables and anyone with half a brain doesnt break those.  If you keep those figures in mind you wont go far wrong, all the values are actually lower than the cable is actually rated at, but its safer to run cables higher than your intended use.  

Btw, im a trained but not fully qualified electrician, so i had these things drummed into me, and i think the new wiring regs in relation to colours are gogin to kill people.
