So you have (what FRITZ!box thinks) ...
352 Kbps download
480 Kbps upload

Is that correct?

What are your real values (as measured during a real download/upload)?

Here my FRITZ!box 7170 values:

Code: Select all

Leitungskapazität   kBit/s     4036       1056
ATM-Datenrate       kBit/s     2304        288
Nutzdatenrate       kBit/s     2087        261
Latenzpfad          interleaved   interleaved
Latenz 	ms        4             4
Frame Coding Rate   kBit/s       32         32
FEC Coding Rate     kBit/s      224         64
Trellis Coding Rate kBit/s      308         72
Aushandlung          fixed         fixed

Signal/Rauschtoleranz   dB  20  18
Leitungsdämpfung        dB  49  28
Status                4ebc   6
I only know that 2 Mbps are guaranteed. 4 and 8 Mbps are considered as maximum possible.

What does Cegecom say?

I did a reatart once of the box to see if it makes a difference in connection values:
I did not ask Cegecom yet, but I think I'll do that tomorrow!

Code: Select all

					Empfangsrichtung  	Senderichtung
Leitungskapazität	kBit/s	408  		572
ATM-Datenrate		kBit/s 	391 		478
Nutz-Datenrate		kBit/s 	355 		433
Latenzpfad				interleaved 	interleaved
Latenz 				ms		15 			14
Frame Coding Rate 	kBit/s 	16 			11
FEC Coding Rate 	kBit/s 	29 			71
Trellis Coding Rate kBit/s 	120 		72
Aushandlung 		adaptive 			adaptive
Signal/Rauschtoleranz 	dB 	8 			8
Leitungsdämpfung 		dB 	43 			29
Status						3ce20 		74
btw, I really don't understand how you get your colums so straight! :evil:

:P (manually)

Your speed values are unacceptable. Kick them ...
Please let us know how this develops ...

Thanks,

I just had the technician on the phone.
He told me the problem Cegecom has, is the amount of repeater stations, so here distance is the issue.
On top of it I have an ISDN line, which apparently uses so much bandwidth (?-never heard of that), that the result is what I have today.
My distance to the DSL station is around 4km. So nothing much to do, except:
- take the cheaper subscription if I anyway do not get the speed,
- switch to Analog, to have more bandwidth available to use the internet.
Anyway we are moving in April, so I take the cheaper subscription and leave the rest for what it is...

Re the moving: Cegecom doesn't even cover the area where I will live so they would have to let the DSL go via P&T.
In that case I might as well go with my whole phone subscription somewhere else...
Anyone a great idea? All P&T or combos with VOX/Tango/VO/Luxembourg Online?
I like to have 2 phonenumbers, so I guess here in LUX I am obliged to kep ISDN?

I just found myself something to do again!

Was the tech guy from Cegecom or P&T (which still is the hardware provider)? You should talk to P&T, not to Cegecom.

With DSL, the last mile is the bottleneck. 4 km is considered as maximum. I have 3.8 and it runs very fast with space upwards. Hence, I don't consider 4 km as problem.

Normally the conditions of the provider states that 2 Mbps are guaranteed. Try to find this somewhere. If yes, point it to them and ask your money back.

The repeater story might be true, but I'm sure they don't want to invest on your branch (not clients enough). The same goes for VOX and Tango. They lend the hardware, and P&T restricts their bandwidth. To me it looks that too many clients are connected to your DSLAM. They should put you on a different port. This requires however that someone switched physically plugs a cable in the DSLAM.

ISDN takes more bandwidth than analog. That's true. therefore, analog DSL has more margins than ISDN DSL, but it is marginal, hence no big deal.

Changing provider might help, if Cegecom has a limited number of DSLAMs available. Check with your neighbors what they have.

All in one FLAT VOX is ok.
P&T also have such a beast. But please do check the different conditions very carefully. They are real tricky regarding flat conversations and add-ons (To provider x, you pay additional, ...). Also check the times where all this applies. Sleep a few nights and read it again.

2 phone numbers, yes, ISDN, no option. ISDN is good. Forget about the bandwidth benefit. Your problem is probably that Cegecom is low cost and P&T restricts bandwidth.

OK, they apparently changed the subscription now ; I got reconnected and now my Fritzbox reads: 460/542.
Tweaktest:

Code: Select all

Actual data bytes sent:	 1024001
Actual data packets:	707
Max packet sent (MTU):	1492
Max packet recd (MTU):	1492
Retransmitted packets:	0
sacks you sent:	0
pushed data pkts:	32
data transmit time:	21.487 secs
our max idletime:	1482.1 ms
transfer rate:	44298 bytes/sec
transfer rate:	354 kbits/sec
transfer efficiency:	100%
I will check with P&T; I suppose the safest course of action is a regular P&T ISDN connection with one of their 8MB products. Most prices seem to be comparable these days. The P&T techsupport will not help; everything via Cegecom. Doesn't simplify matters.
Thx George.[/code]

Hi guys,

I also checked my speed using dslreports.com and here are the results:

Speed Test #81097854 by dslreports.com
Run: 2009-11-02 13:10:47 EST
Download: 888 (Kbps)
Upload: 234 (Kbps)
In kilobytes per second: 108.3 down 28.5 up
Boost: 888
Latency: 114 ms
Tested by server: 2 flash
User: anonymous
User's DNS: luxdsl.pt.lu

And here the FritzBox 7140 results:

Max. DSLAM data rate kBit/s 2332 292
Min. DSLAM data rate kBit/s 64 32
Attainable data rate kBit/s 5416 1228
Current data rate kBit/s 2329 288

So do I have the guaranteed 2mb/256kb or not?
(I have LuxDSL Junior from p&t)

Cheers,

Christian

Hi.

The tweak test is meant tweak the system on the local computer for better performance (by changing buffers). It's explicitly said that it's NOT a speed test. Hence, results might not be correct.

AFAIK you have 256/2048 UL/DL PT subscription. FRITZ!Box says that you are riding on the limit of this subscription. Subtracting the necessary overhead, you will be below 2048 Kbps net data. You're probably on the edge of the 4 km limit (last mile) of DSLAM. Not very much you can do there by tweaking the system, since this will only affect the OS, which is behind the router. The only possibility is to upgrade the FRITZ!Box firmware if this one provides improved DSL modem features.

HTH

Ciao,

Update on the DSL quality! All fine is fine!
Good to check once in a while ...
