Dear all,
I'm currently trying to share an ADSL internet connection over 3 PC's using a modem/router combo. Had a load of problems with flakey connections - fluctuating transfer rates etc...
After a lot of testing/analysis - and a few tech support calls, I think I might know what the problem is.
<b>I was hoping that anyone round here could shed some light on my theory - confirm or disprove.</b>
- We have a single phone line into the house which recently got upgraded to be digital so we can pipe 1mbit ADSL in.
- A previous resident has extended this phone line to almost every room in the building (at least 9 sockets, of which 6/7 work).
- ADSL requires the use of micro-filters on any phones, which we used for 1 phone originally (this fact led tech support to suggest it was a line quality issue), but now use 2 micro-filters: one for each phone.
Phone calls work fine, internet works intermittently - when it works, we get full bandwidth (110-140kb/sec). Just it has a tendency to time out on some pages, fail external pings and tracert's on-and-off...
<b>anyway, my theory...</b> The fact that we appear to have a large amount of extended cabling in this building, is it possible that any noise picked up by this cabling (e.g. from any mains cabling that it runs near to) is interfering with our ADSL signal? even if it's just "dead" wire and not actually used by any devices?
Provided this theory is correct...
- is there any way to diagnose the quality of a segment of line? like you can check Cat-5 cabling for breaks using voltage(?) checkers?
- is there any way of improving the cabling to get a better connection, or will I have to disconnect the extended cables?
------------
Any help is greatly appreciated!
Cheers,
Jack
