speed checks

Den · Jul 03, 2007, 17:14:44

That was on BT tester. Yes I have used Namesco speed test, usually ok but just ran it and download was 163kbps. The exchange is showing green with no problems. MTU set on 1492 (Belkin router ASDL2 with wireless Gplus router) This is the highest setting allowed on this modem/router. How do I check router log/stats?

Den · Jul 03, 2007, 17:19:42

Just rebooted modem and speed on Namesco went uo to 2395kbps. I try not to reboot but when this happens what else can I do if I want to continue?

Rik · Jul 03, 2007, 17:21:26

If both speed tests are playing up, it's less likely to be a tester issue. An MTU of 1492 shouldn't be causing problems, but are both Windows and the router using the same value? How about RWIN, what is that set to?

You can find info on several Belkin routers at http://www.kitz.co.uk/adsl/frogstats.htm.

Can you borrow a different router, or do you have a USB modem you could try with, that would then eliminate your equipment.

You shouldn't need to re-boot to obtain normal speeds, so if you can try a different router or modem, it will help to establish whether the router itself might be causing problems. Is it unduly warm, or is the power supply?

Den · Jul 03, 2007, 18:11:23

Router mtu set on 1492 but windows was set on 1500

Now both set on 1492.

six tests on Namesco are as follows

3771, 2164, 1380, 830, 2161, 3628. all tests taken over 30mins.

Rik · Jul 04, 2007, 09:06:09

I still need to know what RWIN is set to, that setting can have a big impact on speed.

Clearly, with that sort of variation, something appears to be wrong. Normally, I'd expect it to be exchange congestion, but that's been ruled out. At the moment, I'm thinking that you may have random noise on the line and that this is causing errors and re-transmits. Have you been able to get any error count from the router? If not, then contact support and they can run some tests.

Morning Rik

My RWIN setting is 522720 with MTU of 1492.
BT speedcheck this morning of 5335kbps Profile: 6000

Went to computer this morning all lights on on modem/router. Turned on computer, after 5mins returned and Red light on internet sinc and no connection or emails. Rebooted modem, green light came on and thats when I checked speed.

Hi Den

Have you ever tried a different router? I'm beginning to wonder if that's the problem. If you can borrow one, it would be worth eliminating your own hardware. After that, I think you need to talk to support. Clearly, your line is capable of delivering the speed it should, the question is what is happening to stall the router.

MoHux · Jul 04, 2007, 21:07:59

Rik, just now Den said his router was a Belkin ADSL2. If the modulation type is set at ADSL2 wouldn't this cause instability? $:-\$

Rik · Jul 05, 2007, 08:59:29

I suppose it would, Mo. I've never tried it, tbh. Den - have you checked the router settings?

DorsetBoy · Jul 05, 2007, 09:16:42

My routers are all adsl 2/2+,makes no difference at all,they seek the correct settings at set up.

Rik · Jul 05, 2007, 09:22:55

That's what I'd expect, Dorset, but if the router isn't doing that, it could explain the problem possibly?

DorsetBoy · Jul 05, 2007, 09:26:42

The protocols are supposed to be backwardly compatible,more likely to just be a duff router.
Always have a working spare even if it was £5.00 from free ads.

Rik · Jul 05, 2007, 09:31:06

Indeed. The problem I find with supposed to be is that it often isn't. Certainly, I feel that Den would be well served to check with another router. Like you, I always keep a spare.

Den · Jul 05, 2007, 09:49:11

Morning

Just turned on and the same thing I had to reboot before I could get on the net. Then I had a thought, on advice I had run TCP optimizer so I rechecked the settings and noticed that the box for ppp0e was ticked. I un-ticked the box and restarted the computer and it stayed logged on. Could it have been something as simple as that (or simple as me).

Rik · Jul 05, 2007, 09:51:55

If the router was trying to negotiate PPPoE, it could certainly get confused (though I have seen it work). Check in your router interface that the settings are correct.

DorsetBoy · Jul 05, 2007, 09:52:03

Could be,see what happens over the next couple of days.

Den · Jul 05, 2007, 10:37:55

Hi, Thanks for all your help up to now. I will let you know if this as cured the problem over the next few days (in the morning if it has not). Just ran BT test.

Profile 6000kbps
down on modem: 7392kbps
up on modem; 448kbps

Actual : 4371kbps The best so far 5335kbps

So glad I came to idnet. Den

Rik · Jul 05, 2007, 10:44:09

Let's hope this does solve the problems, Den. If not, let us know.

Den · Jul 05, 2007, 17:36:14

Speed dropped and needed to use the web for work (speedtester would not even start). Rebooted modem out of frustation and speed increased. Did BT test and found my profile has been lifted from 6000 to 6500kbps.
contention down was 7232kbps and IP throughput was 5519kbps. Strange but getting better (I think)

.

Rik · Jul 05, 2007, 17:40:08

I'm still wondering whether the router is the cause of your problems, Den. Can you borrow another from anyone?

Lance · Jul 06, 2007, 08:11:21

From reading through this I would also suggest the router to be the problem.

MoHux · Jul 07, 2007, 00:07:03

The reason I asked the question about ADSL2/2+ was because my DLink router has a box to set the modulation type.

This box lists all types covered, but, for dumbos like me it has two sub-headings 'ADSL2/2+ Multimode', and 'ADSL Multimode' (for Multimode read 'Auto').

My logic was that if 2/2+ covered all ........ why put in the other?

Still $:-\$

Rik · Jul 07, 2007, 10:16:51

Valid thinking, Mo, and it could be the cause of the problem. Certainly, at the moment, everything seems to suggest something is not right with the router.

Den · Jul 10, 2007, 17:04:34

Hi all, See I do listen. I could not accept that my 1year old Belkin router could be causing the problems but, just bought a BT 2700HGV modem/router on ebay as recomended. Pluged it in and found it very easy to set up. Then I ran speed checks and found on three tests all were above 5300kbps. Ran Bt test and this was above 4000kbps but noticed that my profile was now set on 5500kbps (why) it has always been 6000 except for one test when it was 6500. How I hand out and receive karmas.
Keep you posted. Another content idnet fan. Den

Rik · Jul 10, 2007, 17:12:13

If the Belkin had generated a low-sync event, Den, it would have dropped your profile. This will recover if the new router holds sync OK. Belkin equipment has a lifetime warranty, doesn't it? In which case, get it sorted by them and either keep it as a spare, or flog it to offset the cost of the new box.
