      Question Two broadband services on the same phone line at once? Very Strange!

      Is it possible to have more than 1 Broadband service running on a phoneline at the same time? This appears to be happening to me.

      I ordered Sky broadband (MID) with Sky Talk and TV a few weeks ago and submitted my MAC to Sky shortly after Sky TV installation.

      Yesterday I recieved my Sky router and was impressed it was on time with everything needed included. I currently use a Netgear DG834G (Sky's router is Netgear DG834GT) for well over 3 years with Freedom2surf ISP (now PIPEX bought it). The routers look physically identical apart from the Sky logo and silver band on the front of the new Sky one.

      Anyway my broadband was working yesterday (still is) with what I presume to be on the freedom2surf (PIPEX INTERNET LTD) service, but I wanted to try the new Sky router out cos I was bored thinking it wouldn't work with my current ISP service. So I plugged everything in and lo and behold I was able to access the net and download things?

      How the hell was this possible? as 5 mins ago it was attached to the old router with the freedom2surf login/pass. I shouldn't be able to connect through on Sky's router with Sky's different embeded login/pass details just 5mins later. I was confused so I started to do some testing on the Sky router DG834GT, started a speedtest:



      The speedtest shows a different IP to the one im used to and it shows the ISP as EASYNET which is Sky ofcourse but how could this be as my Sky Broadband hasn't even been activated yet, I recieved a letter today confirming that my activation date is 2nd July. Sky Talk activation is 3rd July. These are the stats when using the Sky router:

      The downstream/upstream sync (6016/768) looks exactly the same as my freedom2surf service i've been on for the past year, this sync should be closer to (8096/416) if I was truly on Sky's Mid package.

      A few minutes later I then decide to plug the cables back into my old router (DG834G) and it seems to connect to the internet normally, did a speedtest:



      The IP switched back to my Freedom2Surf one, notice the above speedtest confirms that IP originates from my Freedom2surf (PIPEX INTERNET LTD) service.

      The following stats are from the old router(DG834G) that I had to hack out of it as it uses a different GNU library and firmware:

      Notice the line att. is considerably worse in my old router compared to the new Sky router.

      My only conclusion is that there are two separate service signals on my phone line (I only have one phone line coming to my house). But why do they sync at the same speed and why am I even able to connect on the Sky router?

      I think Sky's Sync speed for my mid service will change on the 2nd of July ,when its officially supposed to be activated, to the normal ~8096/416 and change me from FAST mode to INTERLEAVED. If this is the case im anxious that the transfer to Sky's settings might leave me with a poorer service compared with relatively excellent one im getting right now (even as im writing this now).

      Thank you for taking the time to read through all of this, I just had to post as its all too wierd to be left unexplained, maybe there is a perfectly normal explaination to this and me being thick enough not to discover it already.

      this is, theoretically, impossible!! must be mid-migration - or double-jumpered (which is known to have happened)

      I think what's happened is that you are connected to Freedom2Surf using the Easynet LLUStream product, which F2S use to provide some of their ADSL connections (I'm not sure if they provide any new connections using Easynet now, but quite a few people still seem to be on it). Since Sky use the Easynet LLU network to provide their ADSL connections, when you plugin your Sky router you are just authenticating with the Easynet network using your Sky login instead of the F2S login.

      Your current IP address is in the range most F2S Easynet LLU connections seem to be, so I'm pretty sure you are already using the Easynet network for your F2S connection.
