Hi all. Ok Hope this helps some of you 
I had problems with Infinity HH5 and multiple packet drop outs. I could not get the app that accompanies my network streamer to work properly, my ipad and phone were slow and Internet connection dropped occasionally. When my ipad or phone launched a web page, it seemed to do it twice...VERY infuriating.
Ok there you have it. I spoke to netgear for advice on a Router that would replace the HH5 (BTW another problem is that it won't work with certain devices as you cannot fix the IP address with a HH5 unless you have a Business connection)....The Netgear Agent recommended a D6400 (around £150)..Looks great, simple to set up and does all of the following which is vital if you wish to replace Infinity with your own all-in-one router/modem:
- Has VDSL capability
- Allows automatic set-up using simply your btinternet email address that you first set-up when you joined.
- No-body mentioned multi-cast - you need to have this facility to allow your BT internet channels to work. The D6400 has a simple checkbox to tick when you set this up..job done.
- Dual band 2.4 and 5ghz.
Once out of the box all you do is plug all the cables and phone wires in exactly the same sockets..(even coloured the same on the D6400)..load up the free software (Genie) press set-up, Check the ISP dropdown box to say BT (yes ..really, it even recognises that you will use this as a HH5 replacement) check the multi-cast TV box, put in your bt email address and let it set itself up for 2 minutes..and you are done!
Hope this helps.
The only downside is that I only get 60mb wired instead of the 80mb I am supposed to get, however it is still faster that I got with the HH5 and feels twice as quick whist using my iPad and phone...more importantly, my network streamer works now
