Please help me. 4000/400up Cable Virgin media

Technex · Post by **Technex** » Sun Jul 08, 2007 3:18 pm

Hello guys, first post I just wanted to sort out my speed on my network.

1.
I have Cable, using a Cable modem provided by NTL world at the time (Now Virgin media) It's about half a year old. (Doesn't get hot or anything and using Ethernet cable)

2.
My ISP is now Virgin Media UK england, my advertised speed is 4000kbs/400kb upload.

3. What are your current settings now? Do a TCP/IP Analyzer Test and copy and paste the results (remember to XXXXX out your IP address) here.

4.
Using Windows XP pro.

Used to get speeds of around 4000kb download and 400kb upload which is good and what it should be.

Using a Belkin F5D7230-4 v6000 Router latest firmware and all correct settings. This computer is connected directly from the router. No wireless.

Thanks.

Wow

That's pretty good, I remember having 3970 before though hehehe, but don't worry about that small difference if it works every time

.

Thanks, worked nice but I'm a little worried about the:

LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1

Does that mean it just puts all webpages at the top priority, I mean I just want it nice and balanced for gaming and web applications

.

If my understanding is correct anyway :P.

And about my router what can I do to improve that, I can't seem to find any net settings on it other than the basic normal stuff.

Any other tweaks? Thanks very much

MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

Why is it saying that

Why is it saying that

I think your router is limiting your MTU or MSS.

Log into your router to make sure MTU or MRU is set to 1500 and MSS to 1460. After reset, save and reboot the router. These are settings for Cable Internet.

Thereafter, run the TCP Optimizer settings I gave and see if your MTU becomes 1500 and TCP Window becomes 128480.

You can try 5,6,7,8 (TCP Optimizer recommended) instead of the all 1s that I gave and see which setting performs better.

Technex · Post by **Technex** » Tue Jul 10, 2007 5:06 am

Yeah I think that also, problem is I can't find the MTU/MRU/MSS settings anywhere in the router setup home page... I've looked in every single place.

I've googled for it "Belkin F5D7230-4 v6000" but no luck

.

trogers · Post by **trogers** » Tue Jul 10, 2007 6:41 am

Download the User Guide at this link:

http://web.belkin.com/support/download/ ... le_id=2063

Check and ensure your connection set up is for Dynamic IP and not the one for PPPoE as shown in page 30 of the User Guide.

If properly setup, your MTU would be 1500.

Technex · Post by **Technex** » Tue Jul 10, 2007 7:26 am

It's on Dynamic:

TICKED (A Dynamic type of connection is the most common. If you use a cable modem, then most likely you will have a dynamic connection. If you have a cable modem or you are not sure of your connection type, use this.)

+rep btw

Check with your ISP tech as to whether you need to enter a host name and clone the MAC address of your PC into the router as mentioned in page 30 of the User Guide.

Technex · Post by **Technex** » Tue Jul 10, 2007 12:09 pm

Umm, any way other than phoning them? Were not really that keen of there custom service/phone line. And my dad's out atm he's the one with all the info on the account.

I can clone the MAC address I'm sure I've tried before but I'll do it again now.
Argh good job I saved this message my router messed up while cloning the MAC this time for some reason it went crazy I had to reset all the settings. Anyway back to all the right ones now, and the MAC clone worked this time.

Now I get:

TCP options string: 020405860103030101010402
MSS: 1414
MTU: 1454
TCP Window: 128674 (multiple of MSS)

MTU Discovery: OFF
TTL: 47
Timestamps: OFF
SACKs: ON
IP ToS: 00000000 (0)

MTU = 1454
MTU sometimes used in PPPoA applications. If not, consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1414
Maximum useful data in each packet = 1414, which equals MSS.

Anyway is there any other way of finding the host name?

And thanks

.

trogers · Post by **trogers** » Tue Jul 10, 2007 12:33 pm

Your ISP may or may not require a host name. If required, they would have issued you one. Only way to check is to ask them.

Your MTU is now set to 1454. This is a setting for PPPoE. Go to page 32 of the guide and try setting MTU to 1500. If your line disconnect when MTU is set to 1500, go back to this page and reset it back to 1454.

Technex · Post by **Technex** » Tue Jul 10, 2007 12:36 pm

Would the hostname effect speed? If not then it's working fine without it.

There's no option to change the MTU anywhere

.

trogers · Post by **trogers** » Tue Jul 10, 2007 12:42 pm

Then I am out of ideas why your MTU is set to 1454 for Cable Internet. But if your speed is near to 4 mbps, I suggest leaving it at that.

Technex · Post by **Technex** » Tue Jul 10, 2007 12:50 pm

Humm, but why :S. I don't know why it won't let you change the MTU. Is there some kinda 3rd party software which can change it mate?

Thanks.

edit: Like what the!

trogers · Post by **trogers** » Tue Jul 10, 2007 12:56 pm

TCP Optimizer would have set MTU in your registry to 1500.

It may be limited by your router to 1454. One way to check is to connect your comp directly to the modem and run TCP Analyzer.

Technex · Post by **Technex** » Tue Jul 10, 2007 12:58 pm

Yeah I'll do that just after I post this message.

A interesting thing is that if I set up my connection type in my router settings to PPPoE connection it will then let me change my MTU size up to 1492... But why not with cable?

hold on while I swap all cables around :P.

trogers · Post by **trogers** » Tue Jul 10, 2007 1:12 pm

Make sure your modem is placed a few feet away from other electrical devices including the router. Turn power to the modem off for a few minutes to let it reset itself.

Technex · Post by **Technex** » Tue Jul 10, 2007 1:17 pm

I'll turn off my modem now, I'll be back in about 5 mins then. I'll test as soon as it comes back on.

My modem's under my computer it has about 15cm of clearance, no where else to put it.

What about the router's settings not working

?

Anyway brb mate.

Edit: Okay back same modem only after 4 mins or so:

Seems the modem is being affected by electromagnetic interference as seen in irregular ping times at hop 1.

Try shifting the modem and see if you can get all 3 ping times at hop 1 to level off at 8ms. Place it on the floor if necessary.

Technex · Post by **Technex** » Tue Jul 10, 2007 2:13 pm

It's on the floor. Are you sure it's electromagnetic interference? It just seems a little strange that it drops from 4000kbs to 1000kbs just from that :O.

I can't really move it as it's on the floor already under my PC though. If it is this to blame then maybe some kind of metal shield? I dunno...

Yes, EMI causes wide fluctuation in speed and latency as observed in the past posts of members. Constant slow speed is usually caused by defective hardware or wiring, but speed do not swing widely.

That's a 4db filter (Forward Path Equaliser) on the modem there. The metal thing, a engineer put it on there after we called him out about low speeds. Think it's wise to keep it on there?

I wrapped all them cables there lately to see if it would help airflow it has done slightly, but I was getting slow speeds before anyway. It looks messy but I mean where else do you put them! :P

My speed today, a few mins after taking pictures:

Thank you

Edit, I moved the modem all the way over to where my feet is, no electronics around there, without the filter (All nice tight connections) I still get this speed:

Moved (same place as last test) with filter:

Something very wrong here

The photos show 2 source of electromagnetic interference:

Coiled power cables
Sub_woofer

In basic electricity, we studied that a current that passes through a coil of wire will generate an electromagnetic force, the principle of a motor. As it is only a 3-wire power cable, uncoil the cables and cut off the excess length and rewire them to the 3-pin plugs (green for earth, brown/red for live and blue/black for neutral - remember which colour goes where).

A sub-woofer holds a strong magnet inside it. Uncoil your signal cable that is connected to the modem and place your modem a few feet away from the sub-woofer, along the wall leading to the steel support stand.

Technex · Post by **Technex** » Wed Jul 11, 2007 11:28 am

Yes I remember the days when I used to make those cool elecromagnetic lifters with lots of coiled wire. Damn took me a while wrapping that all up. I don't know where else to put it that wouldn't restrict airflow/get in the way.

Ohh I tell you, I would love to rewire them

. If it wasn't for my dad I would have already. I'll have a talk with him later. You see not all them cables are power one of them is there Cat5/e? cable for the modem.

There's no speaker there, that's my case for my computer (I'm into overclocking their's to large fans there). Sorry I should have made it clear, http://www.foramax.hu/images/Aerocoll%2 ... k-45-1.jpg.

Whereas it may look like an improvement the upload speed has reduced. And download changed to lower/higher on every test.

Log into your cable modem and check the signal levels and compare them with those of this thread:

http://www.speedguide.net/faq_in_q.php? ... =92&qid=78

If your signal levels are too weak, then the filter should be removed.

Ntl:250

http://www.cableforum.co.uk/article/141 ... band-modem

I don't think you can get settings on it.

Also: TCP window: 115000 is that good, because I get latency of around 200 on all the servers I visit.

I used:

4000/kbps
x delay 230
= 115000

So 115000 is good?

Also I edited my post back, I added a shield and talked about the cabling.

You also need to make TCP Window an even multiple of MSS.

MSS = MTU - 40 = 1460

115000/1460 = 78.76

Use 78 x 1460 = 113880

Get those cables (power and signal) uncoiled and separated and then turn power off the modem to let it reset before reconnecting and test speed.

With filter is better as it lowers the power levels of both downstream and upstream.

Yep but Upstream transmit Power Level is very high still...

Shall I get a 6db one somehow?

Anything else to do, it seems like EMI isn't really effecting my modem after all.

Upstream transmit Power Level : 46.0 dBmV

These are the values with the filter and they are all within good ranges.

If EMI was not the cause, what was the cause? I suspected EMI affected your modem, not router.

Yeah but would a higher filter be better?

I didn't mean to say router sorry, I meant modem. Well it's just strange how moving it all the way out and also adding a big metal shield didn't change it

.

Thanks.

I done the http://miranda.ctd.anl.gov:7123/ test. It's far away from me but still...

Did you uncoil the cables? Solve the problem at source.

The NDT test indicates your speed near to 3.6 mbps, which is about 90% of your subscribed speed. Perhaps there is problem at the Maidenhead test server that gives a much lower speed? Try testing in some other test servers.
