I had a lovely set up.

Airport running the wifi network, old Scientific Atlanta modem from Cablecom just connecting to the net and only a network cable connecting them.

I could get 7Mbps file transfers to the disk plugged in to my Airport, had port forwarding running nicely to other devices.

Got the new Thomson piece of toilet from Cablecom. get NO speed increase according to speedtest.net but the damn thing is rampaging through my set up.

Has anyone got one of these to act purely as a modem only?

All I want is for the Airport to continue managing my network with no changes to how it was before. I don't want to switch it to bridge mode because I do not want the Thomson box to manage port forwarding, dhcp or anything.

I currently have the Airport in bridge mode with the WiFi on the Thomson turned off. the Thomson is also acting as a DHCP server for the network.

I couldn't get it all to work without the Airport complaining about Double NAT.

Any help would be gratefully received.

Can't you login to the Thomson router and change it using an advanced mode from a router to bridge mode ? I think there is another thread of today on this same router. I have the Ubee now, and used to have the Scientific Atlanta.

That is what I would love to do but I cannot for the life of me find an option to do it.

if I could find such an option I hope that would disable all the network management nonsense.

The other thread is someone trying to log into the machine I think.

In the other thread, there is a link to another thread that might give you the login credentials, supposed to be a combination of the MAC address printed under the router.

Once you are able to figure that out, you might to be able to avoid Double NATting by turning it into a pure bridge modem and let your Airport Express manage the routing.

( am travelling and on a mobile, hence could not link the thread on here )

I am confused as to why the OP thinks speed should increase...

7Mbps sucks though. I would do the normal checks on Antennae , interferance etc , I get 28Mbs through 3 walls at home. OP needs to check channel isolation and location to resolve that, it is not a Cablecom/Thomson issue methinks unless the Airport is Pre-N and not fully firmware patched.

I use my Thomson as just a gateway, turned off the wireless, plugged in my Netgear and everything was just fine. on the FP100, my wireless clients hit 48-50Mbps

I would also start from scratch. Reset the Airport to factory settings, same for the Thomson. Boot the Thomson first , then the Airport , after being plugged into the Thomson, and check the Admin page for both to see if everything is working fine... Then I would work on re-doing all the port forwarding. The Port forwarding should be done on the Airport, and all clients should DNS /DHCP via the Airport.

Many thanks for these points.

OK, just to clarify........

• I can log in to the router absolutely fine.
• Thee 7MBps was between my mac and the USB drive plugged into the Airport. I was well pleased with that speed as the disk performance on external drives is not great with the Airport. Actual internet speed is down from 19MBps to 13. File transfer speed to the Disk is down from 7MBps to 400KBps
• Checking antennae is moot as I do not want to use the Thomson for WiFi.
• Just disabling the WiFi, plugging in the Airport did work but the Airport complained of Double NAT
• I am not worried about the cablecom connection, I just want to avoid using the Thomsons as anything other than a router.

When you say "I use my Thomson as just a gateway", what did you change on the Thomson other than disable the WiFi on the Thomson? Did you change any of the network settings as well?

It's that bit of info that would be really useful. That is exactly what I want to do.

1) External drives , be they USB2/FW400-800 or USB3 should offer a minimum of 40MB/s sustained or around 20MB/s for small file writes. 7Mb/s is just far too low.

2) I changed nothing on teh Thomson, other than disable the wireless. If you have fiddled with other settings, consider resetting both the Thomson and the Airport.

3) I have a sneaky feeling the Thomson is woefully incompatible with the Airport with respect the the Wireless N standard. Is the Airport fully patched ?

Yep, the airport is all patched up.

Believe me, that 7MBps is a damn good speed for a USB disk plugged into an Airport.

I am not worried at all about that. Or at least I wasn't until the Thomson arrived with its uselessness.

I have found this page which is a screenshot of the Bridging page on the Thomson:





Apparently it needs the Mac Address of the Airport but what concerns me here is that I don't want the WiFi on the Thomson to be on at all, yet this Bridging only appears to be wireless, not through the Ethernet cable.

Anyway, thanks for the suggestions. i think I am resigned to a weekend of tweaking, losing connection and resetting!

I might just call Cablecom and ask for the Ubee (if that is modem only).

Thanks again.

Don't waste time trying to bridge, Wireless bridging is notoriously slow if encryption is enabled etc.

Your Airport should just be plugged into the Thomson LAN port, it should DNS and DHCP off the Thomson. All other clients should DHCP/DNS off the Airport.

All should be automatic. Try not to fiddle with these settings. As I said before, reset all, and let themselves sort each other out.

Nice info, thanks.

I'll give all that a go. Thanks again.

Hi Buono,

did you eventually manage to solve your problem?

I have just received the Thomson WLAN router from cablecom and I am facing exactly the same issue. I need to set my airport in bridge mode otherwise it does not connect to the internet. This is not i want, as i would like the Thomson router to act as a modem only and let the airport managing my network (ie, port forwarding, DHCP lease...). This was my previous setup using the Scientific Atlanta.

Any help is much appreciated - I spent a couple of hours with little success...
I am tempted to call cablecom and ask them to reactivate my old modem.

Cheers, Alvise

You probably have a Thomson TWG870U

Here's the user manual:
http://www.upc-cablecom.ch/original_...870_manual.pdf

See page 73:
Your TWG870U can be configured in 2 main modes:

CM = Cable Modem, the modem behaves as a bridge, it has no DHCP server. WiFi is not used. You add your own router after the TWG870U

RG = Residential Gateway, the TWG870U acts as a normal router and assigns IP addresses via DHCP, WiFi can be used.

The manual says:
All units ship from the factory set for the RG mode, but a configuration file which the cable company sends the cable modem section during its initialization can change it.

You need CM mode.
So ask upc cablecom if you can change the TWG870U from RG mode to CM mode.

For future reference in case anyone encounters the same problem - there is no need to call upc cablecom to set the router as a simple bridge. Just connect to the router, go to 'switch mode' and disable it

I've tried it out and it works. I've connected the apple timecapsule directly to the thomson thing via an ethernet cable. DHCP, router, port forwarding are now all handled by the time capsule (and it works!).

Alvise, apologies for not replying as I am on holiday but yes, the steps here worked for me.

The cablecom man confirmed it was ok to do.

I have this modem7router as well. I am able to log into the router, but does anyone know where i can change the primary and secondary DNS....i would like to do a DNS proxy so i can watch hulu and netflix on all my wifi devices.

Made this change today and it fixed the problem I have had downloading video from Itunes since I got this new modem..

There is also reference to that in this support thread

Nice to know that Cablecom, as this has been an issue for us since last October (where suddenly nothing would download properly from Apple or iTunes), has been so unforthcoming about the issue. We called a few times, but we got zip for support. So...if I understood the folks in the forum correctly, there's no fix for the bug forthcoming yet? I've only got a week or two of internet left from them so I'm not sure why I care, but I really do miss being able to rent movies from iTunes and it'd be a nice way to kill time while we circle the drain.

Did you read the cablecom forums, where the problem is very well explained, and where the cablecom technical guys also participate and explain the problem?

In the forum it says that the manufacturer made a new version, the new version was tested in February 2012, and had a lot more problems.

So the manufacturer is still working on fixing the problem, and cablecom won't release a new version until it is fixed.

Yes, that's the gist I got from the German...just wanted to make sure I understood that correctly. Ah, well, at least I know what the problem has been now instead of wondering. I may say something to Cablecom when we drop the kit off before we leave as we've called and they've really offered no support which is puzzling given that thread as they certainly appear to have been aware of it.
