I have used Fritz!Boxes now for over 4 years and the 7490 since March. The 7490 is a much-improved 7390 and it has never missed a heartbeat on my 80/20 connection. I am currently running the latest beta firmware which I updated on 31 Aug. I am getting max speeds on an 80/20 connection with a negligible error rate. If you do not need all the 7490's functions then I suggest that you look at the 3390 which retails at just over £100. It has the same GUI as the 7390/7490 and is future protected with G.INP and vectoring.

Yes but very bad support from them (germany) and not very easy to set up VDSL2.

I can only conclude that you have never set up a 7390/7490. It requires nothing more than your ISP account/ password, VLAN, PPPoE and VCI.

AVM always respond to support questions in English, and their site has an excellent knowledge base. Which other manufacturer would replace a 2 year old box without demur. The 7390/7490 have been through Martlesham Heath.

See the AVM interview on ISPReview.

there is lots of info on kitz forum about the chipset in the 8800nl (same as the zyxel), I got the zyxel now on my line.

it definitely syncs around 2mbit higher on mine and similiar lines, I normally in the evenings get a few errored seconds that have high errors. These have now also occured on the zyxel, I think prior to those errored seconds the error count was lower than the hg612 but now with these it may be higher, but the actual ES isnt higher so far, and I think DLM looks at ES rather than CRC count.

adslmax is very lucky to have such a good connection (even if he's sometimes not happy about it )

I would be interested if anyone is using it on a long(ish) FTTC line.
I'm only getting 23Mbs atm on a 680m line using the OR ECI modem (started off around 30).

Not quite as long as you - my line's around 600M.

But my Billion 8800NL gives me 53 Mbps down, 11 Mbps up, with no interleaving (and it's still slowly speeding up, as it's recovering from a line fault that caused me to swap the OR HG612 back in for the engineer visit.
The HG612 was giving me 45 down, 10 up, under identical conditions.
Those are measured throughputs, not sync speeds, as the HG612 is still locked (I'm preserving one in OR supplied state to use in case I end up in a dispute situation with a fault - I want one that they can see hasn't been messed with.
Sync speeds on the 8800NL are (currently) 55886 kbps down, 11166 kbps up, no interleaving.
So you may be losing out somewhere (although that may just be that your line suffers from more x-talk or something)
Certainly I found the 8800NL to be a worthwhile investment.

It will also only work on a single public IP address, so is no use at all if you have to route a subnet.
I had to send mine back for that reason - support wouldn't talk to me without a serial number to register, so I didn't find out that it is a router that doesn't route (only work as a NAT gateway) until after I'd forked out for it
I wouldn't have minded if they'd made that clear on the sales information and technical specifications.

Is it not a bit irritating that three of its four LAN ports are only 100Mb?

Not in the least.

The VDSL line won't go as fast as that, and for internal network use the gigabit port connects directly to a managed 16 port gigabit switch (which also has another couple of GbE switches and a WiFi access point connected to it, but that's another issue).
It then leaves the 3 10/100 ports for devices that need public addresses - and are limited not by the speed of the port, but that of the FTTC.

I suppose if you only have the router as your network switch it might be an issue.
But I have way more devices on my network than that

Mine was already configured when I updated the firmware, and on upgrading, it offered the option to restart with existing settings or with factory settings.
I chose to reboot with existing settings, so didn't have to change anything.

Thanks for that. I seem to be nearly at my lowest 'impacted' estimate

There's no more I can do with my internal wiring so I may be unlucky.
I'm in a rural situation with overhead line etc.

It would be good to get back to my original 30Mbps. I'm guessing DLM has seen my line as unstable. With my ECI modem I'm running blind (sync/errors/snrm) so will upgrade when I'm able.

Billion alway recommend updating the firmware using the factory settings option just in case the internal configuration tables have changed which could bork the router if there are any of the previous settings end up with invalid data in them.

adslmax,

I'm interested in your comment about using the OR power-supply brick with the 8800NL rather than the Billion-supplied one. I'm contemplating getting an 8800NL and wouldn't want to risk the integrity of my existing home network setup, with its myriad pieces of kit and numerous cables, by getting RFI needlessly coupled into it. But what actual hard evidence do you have that the Billion-supplied brick generates the DC with a lot of noise on it or otherwise radiates a good deal of electrical noise?

It's not that I disbelieve you or anything, it's more a matter of how you managed to fathom that the Billion brick was the culprit. Many power-supply bricks now incorporate small switching regulators, to alleviate efficiency concerns and heat generation. The switching frequencies are usually high, but if the brick meets the requisite regulations it's supposed to not generate potentially troublesome electrical noise, whether airborne or through the DC lead or back through the mains. As I see it, therefore, it's entirely possible - though somewhat surprising - that what you may have observed while using the Billion brick is an unpermitted level of RFI.

The only qualm I'd have about using the OR brick in its place is the possibility that some other aspect of the Billion brick's performance isn't met by the OR one, or the equivalence is marginal. So, personally I'd only use the OR one if 100% convinced that Billion's does generate troublesome amounts of RFI.

Do the OR and Billion bricks have exactly the same current (amperage) ratings?

Do you know of anyone else who's had some evidence of the same problem and has solved it in the way you suggested?

I imagine that adslmax discovered that his power supply was causing interference by the same method that I used. I had a DLM intervention on my FTTC for many months, as shown by my unlocked BT modem. Eventually, I decided to carry out a check for interference using an AM radio. I had seen various references to REIN on the forums so I researched it and discovered the advice to use an AM/MW portable radio tuned to about 612khz. Fortunately, I have a "World Radio", which includes MW and also has a metal telescopic aerial. This proved very useful as I could touch the end of the aerial onto all my power supplies and listen to the result. It turned out that the worst one was the one for my Draytek router. That made some horrendous noises. I bought a new power supply on eBay and within a few days the DLM intervention had gone. It's now been fine for about 4 weeks.
