Openreach fibre modem IP address

Hi all
Bit of a noob question I'm sure but I'm having infinity installed this coming Friday and as soon as the engineer has gone I will be ripping out the HH3 and putting my own router in so I want to know if I need to change it's default IP address to make sure it's different from the OR modem.

My current router uses 192.168.1.1 as it's IP. Is that gonna conflict with the OR modem?
I also have a NAS on 192.168.1.2 and a couple of media boxes using static IPs aswell. The rest of my network is just DHCP, which I assume is handled by the router and not the modem anyway.

Cheers!

The modem doesn't have an IP address unless you unlock it (Huawei HG612 can be easily unlocked but ECI is harder). If you do unlock then you can change the IP to anything you like (I did) which lets you look at the stats.

Don't touch the modem (don't even power it off) for at least 3 days after your install. You can play with the router/home hub.

Your own router will need to support PPPoE on an ethernet port but then you can get rid of the HomeHub3 - I swapped in my Draytek 2820Vn without any problem.

If you get faster than 45megabit then some older routers can't handle the speed and slow you down - so make sure you run speed tests from a PC connected to the HomeHub before you swap out.

Yes there will be a conflict. The OR modem (at least the Huawei HG6120) is set at 192.168.1.1. I expect the ECI one is as well, as the same Home Hub is used.

IIRC the Home Hub is set to 192.168.1.254, so if you change yours to that you should be OK.

You are correct that the OR modem does act as a simple modem, although it is in fact a modem/router that can be unlocked and some even use it as a two-port router.

I suggest you do not mess with the modem itself during the first two days, as the Openreach DLM is watching it more closely than normal for stability during them.

(Edit - and stop yours allocating 192.168.1.1. But I expect you already have it set to 192.168.1.3 upwards).

Does anyone know if you have to use the HH3 at all - can't you just connect the Fibre Modem straight away to your equipment?

Thanks

You don't need to use the hh3. Windows and Linux have built in PPPoE (Windows calls it a "broadband connection").

You can use the username [email protected] and leave the password blank (if you can't leave it blank, it'll accept anything).

Yes you can, you just need a pppoe session to establish a connection.

Thanks for the replies everyone, I'll post back with the results tomorrow when it's hopefully all up and running!

Well Openreach guy has just left. I was impressed with him, quite a young fella but very enthusiastic and seemed interested when I was asking him about the tech etc!

Anyway got the full 80/20 sync and he showed me on his test gadget the max attainable rate was 117mbps down and 45mbps up! Pretty happy with that. This was even using the old figure of 8 drop wire which isn't even twisted pair so that's a relief.

I don't have any other line stats unfortunately and he supplied an ECI modem so no easy hacking for me

Anyway I'm going to just leave it alone for the training period.

Here's the obligatory speed test!

The old wire is probably thicker copper, so what you lose due to possible noise pickup you gain in lower attenuation.

It will be interesting to see what the speedtest results are like over night. The figure of 8 wire will act as a wonderful aerial for background noise.

It is a pity that you did not mention it before or I would have asked you to run RouterStats and see what the SNR swing was from day to night.
