Has anybody here done this? I did read somewhere that once the B818 is in Bridge Mode you can't then use 192.168.8.1 to get to the management pages and the only way to get back in is to do a factory reset, is this the case?

I think I might have when I first got it, and am pretty sure you can still use the default IP address to get to the mgmt pages. But don't hold me to that as once I got over the issue with IPv6 addresses I left it alone and it's been fine since smile

It's an easy enough thing to try though if you're in set up mode.

Out of interest, why do you want to do this?

On mine that is in bridge mode it allows me to use http://192.168.3.1/html/home.html to access the admin/mgmt menus

On my B818s I set the IP address for the admin before enabling Bridged mode, I current had one on 192.168.8.2 & 192.168.8.3 on my network.

Well, I've come to the end of my tether with Three 4g, it's been getting worse and worse over the last couple of months so much so that it's almost unusable in the evenings (something like 16:00 to 21:00) with constant dropouts and hanging completely whilst streaming resulting in rebooting the B818 and the TP-Link Decos several times until it stabilises. I had considered trying another 4g supplier but as it happens there was a knock on my door the other night and it was a Virgin sales lady saying that fibre will be available to me in a few weeks and offered 100+mb for £25 a month for 18 months with no equipment/set up/installation fees so I thought why not give it a whirl for 18 months, installation is set for 12th December PM and I will keep the B818 as a fallback if it all goes horribly wrong with Virgin.

I'm going to use the Superhub 3 as a modem and utilise a rather good Asus router that I bought a couple of years ago and has been sitting in a cupboard since I got the B818. I was trying to prepare the Asus for the changeover so that I could just unplug the B818 and plug in the Superhub and wanted the B818 to do the same as the Superhub i.e. act as a modem, on reading up I found that it needs to be in Bridge Mode to do this.

Is that set under ROUTER then DHCP Lan IP Address?

Another option is put the Virgin hub in modem mode and use the 818 as the main router which will then be able to failover to 4G if required. Less boxes keeps things simple!

Correct, just set this first and reboot the router before enabling bridged mode

I've had a few issues with my EE connection, but I am 99% convinced it's been down to mast issues (I've had a few "we are doing work in your area" texts...).

I have also found the B818 needs a reboot every now and then.

However, I 100% found '3' were significantly slower than EE in my area.

That said, for what you want it's now largely moot smile

I don't think you *need* to have them in bridge mode to do what you want to do.

That’s interesting. For the last 2 years we have been using an Huawei b818 in the loft connected to 3 Apple AirPort Extreme’s around the house (‘base’ unit via cat6 and 2 on ‘extend network’.) When I put it all in I just connected the b818 to the ‘base’ Airport via cat6, put all the Extremes in bridge mode and then deactivated the wifi in the b818.
I’ve always wondered if the b818 should be in bridge mode and the Airports in DHCP mode. I am a complete novice so trying to understand why bridge mode would be beneficial?

Update:
All working now OK. I installed the ASUS in the shelf unit that the B818 is in and plugged LAN cable in LAN1 on the B818 and into the WAN port on the ASUS, my Heatmiser network box and TP-Link Deco into LAN ports on the ASUS. I changed the SSID’s in the B818 and put the old SSID’s into the ASUS so as far as my other kit is concerned nothing had changed, it all works now.

Apparently doing it this way causes double NAT but there doesn’t appear to be a problem with this. When the Virgin box arrives I can just unplug the B818 and plug in the new box. I won’t keep the Three contract as it’s more expensive than the Virgin service (initially anyway) and it’s a waste paying something like £27 a month as a just in case. I wiill lose the ability to have a landline ‘phone plugged into the router but that was very rarely used anyway. If I feel the need for a “land line” then I’ve got a box that you can plug a SIM card and land line ‘phone into so that the ‘phone can be used ( land line ‘phone on the mobile network) and I’ll get a GiffGaff payg SIM.

As long as only one device on the network is dealing with DHCP duties you should have no issues.

It almost certainly will make no discernible difference which it is in your set up., so if it's all working as you want, don't change anything (don't fix problems that aren't there smile).

I suspect the WAN port on your ASUS may also act as a LAN port...but...

What IP address have you given your B818? And what IP address range does your ASUS serve?

If you give the B818 a reserved address in the ASUS range you can then plug it into one of the LAN ports on the ASUS which, if it's happening, would remove one of the NAT legs. Chances are, however, as above it will make no discernible difference (and will use one more LAN port on the ASUS).

The B818 is 192.168.8.2 and uses the 192.168.8.x range and the Asus has ip addresses in the 192.168.1.x rage. The only way I picked up the double NAT was a message in one of the Asus management pages telling me that some functions will not work due to double NAT other than that everything seems to be OK. It's only going to be like this until 12th December when the Virgin service is due to be switched on.

Thanks for that. One thing that is annoying is that sometimes the internet slows down to a crawl until I reset the b818. I then look at the history and it says there was a ‘port scan attack’ right at the exact time it slowed down.

If I used the b818 in bridge mode and used the airport in dhcp mode would it reduce the attacks?

I doubt it. The attack is coming from outside your own network against the routers externally facing IP address, the one your provider allocates.

I would give your provider a call the next time it happens and ask them what can be done about it.

If you were to give your B818 a manually assigned 192.168.1.x address and plus LAN port to LAN port it would get rid of that "issue" (should it ever prove to be one). Not sure what configurability the Virgon box has though so you may not be able to replicate that.

Again, I doubt it would make a massive amount of difference to you if it's working as you want now. But might be worth bearing in mind should you have weird issues later.
