BT Hub 5 and IP address changing

You need to fix the IP addresses in your new router. Hopefully the place to do it will be easy to find. 

the 172 has IP address 192.168.1.64,  my nas sees the 172 IP address as 192.168.67 so how would this have occurred?

If you haven't fixed the IP in the new hub, it can assign a new one. The only foolproof way to deal with this is to set the IP manually. When you set the IP, set it for a number outside of the usual range - eg my SuperUniti is .....110 and the UnitiServe is ......120.

"...a slightly different IP address..."  is like being  "slightly pregnant".

How are your IP addresses allocated - are they fixed (by you) or is DHCP used?

If it's a new hub (using DHCP), you should shut down everything on the network, turn on the hub, give it a couple of minutes to stabilise then turn on the NAS, again - a couple of minites to stabilise, then the 172XS.

IF doing this doesn't do it for you, then my advice would be to switch to fixed IP addressing - managed by the Home Hub, of course.  I take it you don't have any other device on the network that can act as a DHCP server (thus giving out its own set of addresses in conflict with the home hub?).  And I take it you can't get inside the MyBookLive and instruct it to forget any previous IP addresses it knew about ?

Hope this helps a bit !

Unless you like looking at router configurations turn everything off altso the router.

To be sure wait about 10 minutes until you turn on the router Again.

Then turn on the router wait until it is alive, turn on the nas, and then the streamer, and they should now agree on what device has wich ip address.

The Next step is to tell the router to always give the devices the ip addresses they have now. This solution is much simpler than assigning static ip adresses to each device, you just have to find the place in the router configuration to tell the router to always give the device the ip address it is using now.

Thanks everyone, I'll give it all a try.

The wonderful world of IPs can really screw you up, without wanting to sound like a arse, if you are not fully up to speed with what happened, its probably best not to play.

The first question would be how is the change effecting you and what do you mean by the IP is different in the my book?

Every device on your network has to have a different IP.

If you mean that the upnp server in your mylive is keeping a register of renderers, then simply get it to rescan then it should pick up the new ip of your naim device.

One other thing, the BT homehubs are crap, they can put as much gloss paint as they like on them, its never gonna work. Luckily like virgin who also have a crap freebe, you can put what you like on. You want a DSL router, such as the bloody awesome asus Ac68U, which will happily hook up to the BT modem, and you can ditch the home hub and live the dream.

rule number one with free supplied hardware from ISPs, its crap.

Indeed. Orange gave us a totally useless Netgear. We now have a DrayTek, and it's rock solid.

I see, every item has its own IP, makes more sense now. Rescanned and seems to be back to where it was before the new BT hub came. Thanks. 

Will look to getting a better router.

Well I am only speaking from personal experience, if its all working well then don't spend out for the sake of it. I have not actual experience of the home hub five, perhaps after 5 attempts they have finally got it.

I just doubt it, thats all

As I say if everything is ticking along well, don't muss!

I would take whatever IPs are allocated now it is working and make them static, so that if you have to power something down it comes back on with the same address and/or more importantly, if you reset the hub it doesn't reallocate new addresses.

Usually the router has a pool of addresses that it uses for dhcp and since dhcp is used you cannot just set the addresses given by dhcp to a static address. I would still go for fixed dhcp addresses, has worked for me for the last 30 months.

Hi, as others have said using your broadband router to assign specific addresses for at least some of your devices is sensible, especially with the limitations with some consumer applications.

The IP addresses should be assigned by an application called DHCP on your broadband router. It is best to always do this rather than manually assign unless you have a tiny LAN. However you can usually tell your DHCP (through the setup pages) to assign a specific IP address to a devices network (MAC)  address.

I am not familiar with the setup screen of BT Homehub 5, but it may list the network addresses of connected devices and allow you to fix them. If it doesn't and prompts you to manually enter the details, the network and IP addresses will usually be found on your NAS setup screen, Naim setup screens for example.

The network address is usually represented by 6 pairs of hexadecimal characters, each pair seperated by a dot.

It is best to do this for only the devices you need, but usually your home NAS benefits from fixed addresses, and some of the smaller Naim devices. 

In my setup, I only fix my NAS IP address (using my DHCP) but everything else can vary and its been reasonably solid for a few years now. UPnP and Apple media apps are designed to allow dynamically assigned IP addresses, and so this is usually fine, unless there are problems elsewhere that you are papering over.

However some consumer implementation of file attachment protocols used by NASs need to know the IP address of the NAS, hence why it is best to keep that fixed.

Finally a word of warning, and I do work in the field, in the UK it is BEST to use your ISP provided broadband router if you are using DSL (ADSL, Superfast) unless you really know what you are doing.

This is because the DSL firmware on your router is matched to inter operate with your ISP's MSAN (exchange access node) to provide the fastest most reliable broadband connection. if you use your own broadband router ensure it's flashed with firmware that is specifically for your ISP where you are local loop unbundled (most of the UK now). if you don't do this you may suffer from slower than expected broadband speeds or high levels of resync disconnections  if you have a longer line to the exchange. Since the arrival of ADSL2 this has become more important than with earlier slower ADSL protocols.

Couldn't agree more with the modem side of things Simon, but fail to see how this relates to the router, the fair number of times I have done it, the router picks up automatically the wan side IP address from the modem and off you go takes seconds.

BT comes with two boxes, a home hub and modem. Virgin comes with the superdud which can be put into modem only mode.

As i said leave the modem connected but get a better router, this has only had positive effects where virgin is concerned, and infact they show you how on their forums. For BT they suggest you simply phone them for your credentials if you don't know them and that you will loose their btzone thingy.

Same for me Claus. Whatever IP you use or are obliged to use, fix it and forget about it. My HH3 will allow for any assigned IP to be fixed.

Thanks all, at the moment it seems to be back to working and business as usual. That old saying comes to mind "if it ain't broke don't fix it", I think I'll leave alone. 

I have to accept anything that is a computer is gonna be trouble sometimes.

oh how I love my record player, you know I place a record on the platter, lower the tonearm onto the record and music flows forth from the speakers, wonderful progress in reverse!

Home Hub 5 is now modem and router combined in one box, so if you want to replace you will need to get hold of a modem presumably?

In which case I apologise, looks like they are locking that one down, lols. I h ave only recently seen the four.

If the OP is happy everything is working then fair enough. However unless BT offer modem only mode, I wouldn't be going with them for the home hub lockdown alone. The four you cannot even change the DNS.

Hi Gary, the issue with the broadband modem is not at the transport layer, ie IP addresses. It is way below there at the physical level upon with the ATM or Ethernet ADSL link is established. The physical layer on DSL sets the codecs and DSP properties and protocols for the analogue modulated RF that the digital info encoded into. As you can imagine this is the most advanced and complex part of a DSL connection (and the most interesting). To squeeze a relatively high bandwidth link over a single twisted copper pair over potentially relatively quite long distances takes a lot of optimisation and advanced engineering techniques. Now this is where the matching of the exchange MSAN (or cabinet for Superfast) physical layer with your broadband modem comes in. If the physical layers are not optimised, then you should still (though not always) get a synchronisation connection as after all standards are being used, but the sync speed and/or reliability may well be less than if the physical DSL profiles are optimised. 

If you can't  confirm the DSL profiles, and you definitely need a more capable LAN router, you can always use the ISP broadband router as a WAN NTE modem, and connect to your own provided router via Ethernet. This way you should get the DSL optimisation from your ISP and can use advanced routing capability on your LAN if you require it .. But as I said I would not really recommend this unless you know what you are doing or your ISP specifically supports it.

I have had lots of drop outs and problems with a BT HH2.  It was ok with just an iMac computer, iPhone and a Sonos Bridge connected but once we added an iPad, another iPhone, Apple TV, internet TV and my daughter's Macbook it is constantly dropping one or more of the wifi connections, seemingly at random and sometimes even the iMac computer, despite it being hardwired to the HH2. I sometimes get them back after restarting the HH2 but sometimes it takes 2 or 3 attempts.

I use the Fing App on my iPhone to see which devices are connected and what their addresses are and they all seem to constantly change rather than remain fixed.  I have phoned BT several times and they can never sort it out and won't offer me a later Home Hub.

Simon - is there any problem in just ditching the HH and substituting another router - Netgear or perhaps an Assus DSL-N55U N600 dual band modem router (£90 from a well known high street electrical retailer)?  I don't fully understand your last 2 posts but I think you are saying it is usually better to keep the modem element of my HH2 for compatibility with my BT ISP and then plug in a router to take care of the distribution etc duties.  Sorry if this is a bit garbled, apologies to the OP for going a bit off topic, but I am a bit of a technophobe and rather of my depth as far as this stuff is concerned.

Thanks for the explanation.  I understand what you do but I don't really understand how it works - won't you have 2 "competing" wifi routers as both the HH and AE will be capable of routing or does the AE take priority with Apple products?

Shropshire the extreme is quite basic and it can be also be set to just be an access point, i.e. routing is passed back to the main router, in this form its basically a switch with wireless access.

in fact most routers can be set to do this if you want, for instance I have an asus ac68u as a main router (connected to a virgin superhub set to modem only) and attach to this is an asus RTn66u which is a fully fledge router in its own right but has been switched to be access only, and also increases the wireless range much like the airport express. Only better

Another option is to ask BT to take back the Home Hub.  This is what I did about 4 years ago.  They gave me a Voyager 220AV which is a wired router and modem.  I have been using this with an Apple Tine Capsule wired and wireless router since then (previous to this I used an older version of a Voyager and an Apple AirPort Extreme wireless router for about 6 years).   IP addresses are distributed by the Time Capsule via DCHP, so my home network (wired or wireless) is immune to IP address changes by BT.

The only 'issue' I have is double network address translation, but this in fact gives perceived better protection of my network from potential hackers via the internet.  So, I have left it alone (I have tried to co figure the a Voyager to be a modem only, but support is difficult to find either from BT or on-line). 

I do not have experience with Naim streamers, so cannot comment on whether they need a static IP address to work.  Also, I am on the ADSL service, not on FTTC/FTTP. However, it may be a way forward with BT (I.e. Explore if it is possible to have a simpler/different modem or a combined modem-router) If you are unable to switch off its wireless settings or configure to use DCHP etc.
