I upgraded my router to FW1.04 last week to see if it was any more stable with BT Infinity.  Unfortunately it still locks up after a day or two - you can't access the admin webpage or the internet.  Back to using the HomeHub 3 as the router.

Did you follow this and set up the router from scratch after doing the last factory reset?
FW Update Process

Just confirming that you acquired the v1.04 FW version file from here?

Check the phone line cables and ensure they are filtered correctly and signal is correct and to spec. Swap out all cables between ISP Modem, Router and PC.

Any chance you can test this router out at a different location to see if the problem follows? Friend, or Family with similar or different ISP service and modem? Seems like your dealing with Double NAT.
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

If after all this and the problem still exists, then you'll need to phone contact D-Link support for an RMA.

Seems like your dealing with Double NAT.

No they aren't. It would be worth noting that this is a standard configuration across the UK. When a customer signs up for FTTC in the UK our national telco comes out and modifies the master socket. They also install their own modem. This does nothing other than provide a raw Ethernet socket. It is for all practical purposes invisible to the customer and will not normally be visible on their LAN.

It might also be worth noting that in the UK the telco and ISP are rarely the same thing. We have a very flexible system here. The telco owns the physical network but it offers wholesale access to any other ISP that wants it. In fact even though the OP is on BT Infinity and the telco is BT they are actually separate divisions so their ISP is not the same as the Telco

Thank you for your informative information however getting down to specifics with modems, if modems have built in routers and users put an additional external router, such as the DIR-645 or any other router online with these modems with built in routers, this causes a Double NAT condition. Makes things very problematic from a connection stand point.
As the OP stated, the Home Hub 3 they mentioned seems to be a modem router combination as look at various support sites regarding it say that this is an all in one modem/router.

We here in the forums try to establish this information so we can gain a better understanding of users network setups and provide better suggestions in trouble shooting user problems. I happen to have this same model router and it's never exhibited these conditions, however I don't have a modem router combination for my ISP, it's a modem only unit thus the NAT is handled by the 645 only. My modem does support IPv6 however my ISP doesn't so I can't fully test IPv6 until such time as the ISP supports it here.

The preferred connection methods vary however in most cases, we recommend that users try to use a modem only option with there ISPs if possible. If modem only units are not available, then the next step is to bridge the modem if said modems support this feature, some do, some don't. If modems can be bridged then the external routers can handle the connection and single NAT condition which is preferred. If modems can not be bridged then the next step is to use the modems DMZ for the external router, even though there could still be a double NAT condition here, the DMZ usually eliminates most of the modems processing of the traffic effectively puts the external router on the front lines of the connection. Some modems may or may not have this or some ISPs have there modems locked down and users do not have access. If this is the case then users are recommended to eliminate the external router and use a Wireless AP only solution instead of a router since some of these modems are not flexible in configurations, then the need of using a external non-router device is preferred. Such as D-Link DAP series of products. However sometimes a DIR series router can be turned in to a AP only solution which this may work to help resolve double NAT problems.
