I have a little problem to solve concerning my broadband set-up. I get my broadband through a BT ADSL line, though my ISP is diffferent.
My current set up is:
from main socket, then a high pass/low pass filter, with the high pass side feeding my modem, through 20m of telephone wire, which is USB connected to my PC. The low pass side is 50/50 split to 2 telephones. This works tolerably well.
I have a new wireless router which I need to enable me to connect my new PC to the internet (windows 7 doesn't support old modem).
I want to maintain the current wired connection to my old PC [this a highly desirable constraint: I know there other ways of doing it such as buying a wireless adapter for my old PC, or setting up an ethernet], and yet add in the router. The problem is if I split the signal to the old PC anywhere, to enable me to add in the new router, the signal to my old PC isn't strong enough to enable internet connection.
I can't find a bidirectional line amplifier to amplify the signal before splitting [gain <10dB, bandwidth at least ~10kHz - ~15MHz, impedance = suitable (pls advise me)](wherever that splitting is done). Any amplifier must be connector compatible with either RJ11 (as the line enters the house) or RJ45 (for the wire after the filter).
I am in the UK.
