EWAN Throughput maxes out at 34Mbps? (or just with QoS?)

[albany]

beegee,

I think you already have the answer in the ixchariot plots by admin. Depending what settings in the router they used, you'll probably max out at about 60Mbps and I can't see what further test they can do to answer your question. Perhaps just wait and see when you get the FTTP. I'd be interested to know the real-world answer.

Perhaps Speedtest does a slightly different calculation to ixchariot to show 70Mbps+ for BTInifity users on the new 76Mbps service - ixchariot uses averages and as you'll see takes it across 4 pairs in the testing done by Billion (although this is optional). It is a well-respected test but the instantaneous throughput at any one time is not neccessarily going to be 60Mbps. Speedtest also does some averaging so depending on the algorithm each uses, they may give different results from the same data. They'll be ball-park right.

I'd be very surprised if you get close to 100Mbps through this device on current firmware based on that ixchariot result. And don't forget to do so, you'll probably be thrashing the cpu on a passively cooled (but nicely ventilated) box which gets pretty hot in any case in my experience. That may lead to errors and early component failure if you were to run it flat out for extended periods.

Interesting thread as I have just moved over to FTTC 2months ago with ADSL24 and currently on 40Mbps down and 10Mbps up profile using the BT open reach modem connecting to 7800N. So far my results are not bad getting 36Mbps down and 8Mbps up via speedtest.net. Well the speed does fluctuate a bit between 34-39Mbps but it is expected. Just await for ADSL24 for a price to upgrade me on the new profile (yes they are charging extra for this up to 80Mbps upgrade) and BT's site said I should be able to get around 65Mbps.

I have been using Billion since their old 7402 series and have been pretty happy with their QoS and hence I upgraded to 7800N about a year ago. I have quite a lot of devices at my home so QoS was necessary for my Asterisk server (well not so important now as VDSL is at 40Mbps doesn't really cause too much trouble with bandwidth anymore!). However, the QoS rules still exist on the 7800N and the my speedtest result has rarely gone below 35Mbps with the QoS in place. The other reply you mentioned where QoS was removed from the config never really said whether the QoS rules were input again.

Can you remember what QoS rules you setup and what else you think you have setup that might affect the WAN speed? You can contact Billion support but I don't think it is going to be a straight forward reply without giving them some information on your setup or settings. I had an on going issue for a while on my old 7402 series before and was resolved by their support and they were quite helpful so I will suggest given them a go.

Once I get my 65Mbps upgrade then I will be able to verify whether their 62MBPS is valid or not in the real world. I am not expecting a miracle as 70Mbps something average throughput is what I will expect on a 100Mbps port.

I agree that from their throughput test doesn't necessary reflect instantaneous throughput at any one time is going to be 60Mbps as it could be higher and hence they quoted average. The column of maximum throughput was also shown and if you add them together it does show close to 100Mbps. I might run some WAN throughput tests myself on the 7800N if I got time this weekend, if so I will share my results.

Hi billion_fan

Please see my post just above albany's

Do you think the 7800n will be capable of handing off a 100Mbps WAN connection (FTTP) to the LAN at full speed? Or close to?

Thanks

billion_fan,

Correct me if I'm wrong. Given my understand,

1) A 100Mbps WAN connection although quote 100Mbps are never 100% itself. Similar to my previous Be line was quoted 15Mbps and the maximum I ever got was around 12Mbps and my FTTC now quoted 40Mbps and test 36Mbps average.
2) A 100Mbps Ethernet port also will never run 100% e.g connecting two PCs via 100Mbps LAN to a switch/ hub will not get you 100Mbps.

Basically all these WAN and LAN figures are usually maximum obtainable figures in theory or burst speed which doesn't really apply in the real world as there are always fluctuations and overheads. I have yet to find anyone who can show me how 300Mbps is obtainable on 802.11n wireless as usually an average throughput of around 50Mbps depends on the environment is what I got. I don't think I will have much luck either trying to get some explanation on how to get 600Mbps or 900Mbps wirelessly as quoted by some manufacturer.

I think if a 100Mbps AVERAGE (not quoted maximum) throughput is needed then a Gigabit WAN and LAN port is a must.

Any products coming out with Gigabit WAN soon?

Hi nicotine

From the (admittedly few) speedtest results I have seen over on the Thinkbroadband forum, FTTP users are reporting download speeds in the low to mid 90Mbps (not necessarily with this router) Obviously 100% is never going to be achieved (laws of physics and all that!) but I would expect a higher % of the theoretical maximum than with FTTC which is always going to have some degradation due to a run of copper between the cabinet and the user. I've not seen any download figures for very large files though; those speedtest results are likely to be quite "bursty" and therefore skewed towards the top end.

And I agree if the wireless LAN is only going to run around 50Mbps that becomes the limiting factor; and unless I sit all day watching a download meter am I really going to notice? After years of 4Mbps

Yes there are already gigabit WAN routers out there

Hi albany

Regarding your ticket I will drop you a personal email to discuss the matter further.( I checked your ticket and there have been replies, maybe it went in your junk mail)

I have to agree with nicotine, the test we posted was on the average throughput not the maximum throughput, which would explain some customers acheiving a higher throughput then the ixchariot results posted.

Look out for my next post which will show the maximum throughput via ixchariot.

Billion_fan,

Thanks. I'll look out for it. The auto-response and joining emails didn't go into junk and I'm usually pretty good at checking, but it is always a possibility the important emails got lost

Did you get my email I sent??

I will send you a PM, with the email address I sent the email too.

[albany]

Thanks yes. Both received.

Now that my line has Fully trained ...

I can constantly SpeedTest 54mb down and 10mb up


this is through the Billion so can offical say YES it supports past 34mb

[albany]

.

I can constantly SpeedTest 54mb down and 10mb up

Great result!

Can I assume you don't have any QoS settings in place?

Those settings seem to be the culprit here. billion_fan is arranging some more testing to look at that.
