Today I am annoyed with myself because I didn't notice the obvious problem and therefore solution. So it started today when decided to investigate why on my sky box, the vault and a handful of other channels breakup where as in other rooms on other boxes they don't.
I assumed that my box might be more sensitive to a good signal, and merely the dish was slightly miss-aligned... with this in mind I carted my Box and a TV out to the garden made up a quick sat cable to reach from the LNB to the Box and shimmied up on the roof to try and get a better signal / quality (remembering to take the card out the box first). I turned the box on and went straight to the Vault, and the picture was perfect... Ok it must be the cable run.. so I will try and get an even better signal here and it might work in my room... I did get a much better signal so the dish was miss-aligned, but on plunging it back in where it belongs the picture instantly started breaking up again... about 10 seconds of googleing later I read that DECT phones and WLANs can interfere since they all occupy the 2.4Ghz Frequency... This is where I feel really stupid... I know DECT phones and WLANs use 2.4Ghz and I also knew that the SKY frequency was the same... though I never put them together... I knew DECT and WLAN can interfere with each other...
So after moving the WLAN and DECT phone from their home right next to my SKY Box its all a-working properly...
funnily enough both the DECT phone and the WLAN are installed because I'm now a councillor... the Council paid to have the WLAN in, they won't let us use our own connection, for security reasons really but it does seem a bit of a waste of tax payers money... since I now have two WLANS in my house... I'm not about to get rid of my personal one... The DECT phone and line I bought and paid for to keep family stuff and council stuff separately... interestingly its the DECT phone that has the biggest effect on the SKY box...
The Vault is a cracking channel, plays all the top tunes from late 80s to late 90s... Now I can wander form room to room and hear the Vault in all its glory!
