Wireless router interference

[paulw]

Hi everyone,

I have just started back on the air after many years and am having trouble with RFI between my rig (FT1000MP) and my router (Belkin Wireless). The problem appears to be that when I tune the rig on any band from 160m upwards the router looses its internet connection. Has anyone had a similar problem or can anyone offer a solution.

Many Thanks

I get a similar problem but for me it's limited to 80m. The problem in my case induced noise on the phone line feed to the router. Ferrites on the power and network leads have made no difference. I haven't tried but I would expect a ferrite on the phone line to block the DSL as well.

Monitoring the (Netgear) router while transmitting shows the s/n ratio seen on the line drops to 0dB when transmitting.

One thought is to try a low pass filter at about 2.5MHz since that should allow the ADSL frequencies (1.1 or 2.2MHz) and block everything except top band (I've got a 30' garden so I'm not even trying top band!)

Buy a Phillips SN 2600 series router!

Mine sits about 3 ft away from the rig/linear and has no problems whatsoever

Thanks for the replies both.

Since my post I have re-wired the house telephone wiring in CAT5 cabling. This is guaranteed as twisted pair whereas my original wiring was done in non twisted pair cable. I have also disconnected the ringing wire (I think it was pin 3 on the BT socket) as I do not need it. Both these made a vast improvement with interference now only on 20m. I have now cabled the router direct to the BT master socket where the adsl splitter is plugged in. This has reduced the interference to virtually zero.

I too noticed the noise level on the adsl signal increasing. In fact when I changed the house wiring the snr improved from 13db to 25 db so there was obviously alot of stray pick-up. I have found out that BT produce a plate that fits onto a standard NTE5 master socket, which effectively cleans up the house wiring. I'm not sure how good it is but have a look on the web for it. It's called the I-Plate.

Hope this helps.
