This may sound stupid but..

Recently my Dad purchased a Samsung Galaxy S3.

And since then, the ADSL connection on our router drops out and/or gets really low line rates. Funny thing is, he's not here right now, and the connection speed is great! I'm waiting for him to come back to see if it affects the speeds at all.

The whole time, I've though it was something to do with my ISP (Slingshot), but today it hit me. We've only been having speed issues since he bought that phone. So, just wondering if it is at all possible for a cell phone to interfere with ADSL connections like that? Or is it just a coincidence that the speeds pick up when the phone isn't here? I just had a visit from a Chorus tech and he found nothing wrong with the phone boxes and modem, have also called Slingshot several times to see if it was anything on their end, and they've not found anything (which is why they sent the Chorus tech around)


Thanks.
