Router problem trying to reach 20Mb speeds?
 

Hey, I have VM 20Mb broadband ( was just updated from 10Mb a few days ago ) When I was on 10Mb I would be able to reach around 10Mb speeds. Now the upgrase has happened I can still only get 10Mb speeds when I connect through to my router. When I connect to the modem itself, that is when i start seeing speeds higher than 10Mb, as soon as I reconect to the router I then can only get 10Mb speeds. Or this is what looks like is happening.

I have 20Mb broadband with a NTL 250 modem connected to a Belkin Wireless G Router ( Belkin Wireless G Router 54Mbps 2.4GHz, version F5D7230-4 ) connected by ethernet.

Any help would be grateful on how to change some settings to allow 20Mbs speeds or if a new router would be needed.

You could try emailing them http://www.belkin.com/contact/suppor...spx?cid=6&bu=2 or even ring them 0845 607 7787

I have had dealings with their Tech Support in the past and cannot speak highly enough of their service.

Re: Router problem trying to reach 20Mb speeds?
 

Ok thanks, I will try that.

Re: Router problem trying to reach 20Mb speeds?
 

Let us know how you get on bud. I may experience the same problem when I eventually get 20 meg!

Re: Router problem trying to reach 20Mb speeds?
 

Belkin seem to be very coy about the specification of the WAN port on this router. A lot of these routers have only a 10-BaseT WAN port which means maximum 10 Mbps. I've had a look at the Belkin website but can't find the spec of the WAN port on this particular router. I suggest an e-mail to Belkin support. You need a 100-BaseT spec WAN port.

Re: Router problem trying to reach 20Mb speeds?
 

Well I have sent them an e-mail, just waiting for an answer now. On the routers box it does say -

Ports
4-10/100Base - Tx auto-senssing and auto-uplink RJ45 ports, ( LAN )
1-10/100Base - Tx RJ45port, ( WAN )

Re: Router problem trying to reach 20Mb speeds?
 

It would appear therefore that the WAN port is 100Base-T capable. It may be that the processing power of the router is just not capable of the throughput required at 20 Mbps. Of course, all routers will slow the connection to some extent. I have a Linksys WRT54GS and can get speeds approaching 20 Mbps through the router. You may have to look at replacing the router if you feel the speed is a problem.

Re: Router problem trying to reach 20Mb speeds?
 

I have upgraded to vm 20mb too and had the same prob. most routers will only go up to around 10mb when wireless. I have reverted back to hard wire for my main pc to get the full speed. i have still yet to find a router that will give you more than 9-10mb when wireless.

Re: Router problem trying to reach 20Mb speeds?
 

Good point Pedro1. I was assuming that shawty is using a wired connection.
I agree that via wireless 10 Mbps would be pretty good. I can only get 7-8 Mbps to my laptop but then it does only have a 11 Mbps wireless network card.

Re: Router problem trying to reach 20Mb speeds?
 

Remember when you are using a router you are stuck behind the NAT settings.
Although i get back my full speed by going back to the wire i also have to set whichever pc i am on to run outside the NAT settings to get full download speed. (ie torrent sites).

You can use port forwarding, or on your router or just go into your routers DMZ settings and set your ip outside the NAT settings.

I am averaging around 18.5mb as when b4 i was 9-10mb (wireless)

Re: Router problem trying to reach 20Mb speeds?
 

All good points again Pedro1 and things you tend to forget about but all affect the max throughput of the router as you say.

Re: Router problem trying to reach 20Mb speeds?
 

Well I am connecting to the router through an ethernet wire, did used to be wireless a while back but found it pretty crap to be honest. And all the stuff you mentioned, I wouldnt have a clue how to change them lol. Still waiting for a reply from belkin.

Re: Router problem trying to reach 20Mb speeds?
 

shawty go into your routers configuration menu.

For Belkin try the local ip of 192.168.2.1 in u r address bar.

Re: Router problem trying to reach 20Mb speeds?
 

Yeah I have done that and got the menu up.

Re: Router problem trying to reach 20Mb speeds?
 

To get your 20MB or so m8 you will need to hard wire the router to your pc.
You will be pushed trying to get past 9-10 mb when wireless, on any router that is.

As far as your download speeds are concerned check your ip then go into your router then into firewall then DMZ settings.

Enter the last of your ip in the box and apply it.

This will set your computer outside the NAT settings and allow you to download at your max.

---------- Post added at 16:53 ---------- Previous post was at 16:38 ----------

As i mentioned set your comp outside the NAT firewall setting and see if that helps any.

Let us know how you get on.

Re: Router problem trying to reach 20Mb speeds?
 

When I get to the stage were I have to enter the last 3 digits in the box, the number that is already there with the space to enter a number, there is only one digit left of my ip and not three. Do I just enter the one number?

Also there is in total 3 computers connected to the router, will doing this also make them computers work at full speed through the router or will i have to do something different.

Sorry i realise you said last and not last three, im not with it today. Ill give it a go now.

Re: Router problem trying to reach 20Mb speeds?
 

You can only set 1 comp outside the NAT at a time.
And yes just the last digit of your ip is required.
Go into start then in the run menue type cmd.
When you get the black dos screen type "ipconfig".

Look at the ipv4 address and you will see your local ip as assigned by your router.

If all comps are running each will have a different last digit, check each by using cmd ipconfig and change as you please although remember only 1 comp or 1 ip can be placed outside the NAT at any 1 time.

Re: Router problem trying to reach 20Mb speeds?
 

Doing that has just seemed to slow it down to about maybe 5Mb. I am running through a wired connection.

Well it seems to of gone back up to about 10Mb but stil not getting anything over 10Mb.

Re: Router problem trying to reach 20Mb speeds?
 

If you are able or have a long enough cable, bypass your router and connect directly from modem to pc.
Check to see if you get full speed doing that and then we can take it from there.

---------- Post added at 17:48 ---------- Previous post was at 17:44 ----------

Do a cable forum speed test when the router is bypassed and note the result or go to www.thinkbroadband.com and do a test there, we need to see that you are getting more that 10mb from your isp.

In fact go to this link and take the very last file and download it, the one at
1348M.
leave it running for a couple of minutes and report back what your download speed it ie KB/sec

Remember to do this without the router to establish what you are getting from your isp.

Sorry for the delay. As you can see though from the speed test on here, as soon as I connect straight through to the modem the speeds do go up, now if i connect to the router, i will never get over 10Mb.

From the link you gave me I downloaded for a few minutes from a file that was 1400M and got 320KB/s.

All though the results are muddled I can confirm that I have never had over 10Mb through the router were as I have with the modem.

Restarted modem and getting 1.01MB/s on the same file.

Modem config page confirms Im on 20Mb.

Just spoke to my dad and his laptop downstairs connected to the router can get up to 14Mbps when doing a speed test from this site. normally 10 and 11's and most the time averaging around 9Mbps because of the first or last test it does out of the 4 being slow.

Re: Router problem trying to reach 20Mb speeds?
 

shawty, I'm having a similar problem. Connected to modem directly and I'm nearing the 20Mb, but through router I never get above 10Mb. Thinking its a problem with the router. Can anyone tell me a router that can deliver the 20Mb?

Re: Router problem trying to reach 20Mb speeds?
 

shawty i am currently using the same router as you and don't get restricted when wired. Only get restricted when wireless.

I have just wired my laptop to the router and it is restricted to no more than 10mb. Yip even with the wire.

I am starting to think that this may be a network card problem.

Now i have the same prob but only with the laptop.

Try sticking in another network card and see if it makes any difference,
failing that not quite sure.

Re: Router problem trying to reach 20Mb speeds?
 

Ok, thanks for the help anyway. I will struggle along with 10Mb for now as Im quite busy with stuff at the moment. But if I do end up getting it fixed I will let you know.

Re: Router problem trying to reach 20Mb speeds?
 

Having been busy and have got a broken wrist i just couldnt be bothered with sorting stuff out lol.

Im going to do the stuff Belkin told me to do soon but just need to ask a question.

Ive got this network card.

Realtek RTL8139/810x Family Fast Ethernet

When i look on EVEREST Home Edition, it shows the connection speed as *10Mbps.*

*Now is this the reason why im not seeing anything over 10Mbps when im on a 20Mbps connection and if so how do i change it?*

*Edit -

Uninstalled it, restarted computer, installed autimatcaly, looked on EVEREST and now it is showing 100Mbps, so that fixed that as it was showing 10Mbps but the problem still continues regardless.*

So is the network card good for 20Mbps?

Re: Router problem trying to reach 20Mb speeds?
 

Also will cat 5 ethernet wire handle 20Mbps?

Re: Router problem trying to reach 20Mb speeds?
 

I have the same problem of only 10mbit through the router (SMV7004VBR), through just the modem (NTL200), approx 17 to 18.
Left a post on another part of the forum and a kind gent pointed me to a website that stated that my WAN port on the router was only rated at 10 base T and not10/100 base T as in the instruction manual.
After 3 very confusing calls to SMC (India me thinks), they told me that it was indeed only rated at 10. So I am off to get me a Linksys WRT54GS, although I will only be using the wired side of it, patrners son can use his laptop:)

Re: Router problem trying to reach 20Mb speeds?
 

Shame mine has got 10/100 base-Tx.

I myself tjhink it must be the router on its final legs.

Re: Router problem trying to reach 20Mb speeds?
 

Yes, it will handle 100Mbps. Cat5e will handle 1Gbps. Cat6 will handle, well, more than 1Gbps.

Re: Router problem trying to reach 20Mb speeds?
 

Cheers thought it would.

Re: Router problem trying to reach 20Mb speeds?
 

Had the same problem..SMC7004VBR.......manual said WAN port 10/100 but not the case after this forum (nice peeps), was told only 10. Was advised to get a linkseys router so ordred it via on line PCworld for instore pickup (cheaper) £48.70, when instoe advisor said get the Belkin....F5D7230.....as I will at this time only be using the 'wired side' of it. Installation not a dream but if you read the pdf manual first rather than the 'Quick set up' it works. Cannot comment on wireless but for wired it breezzes. TRy reinsatlling.

Re: Router problem trying to reach 20Mb speeds?
 

Havent resolved this issue officially yet but have got Belkin to send me out a new router based from what they have said here.

"Good Afternoon.

Thank you for your email.

The reason why your are seeing a slow down when connecting the router is that the routers firewall is blocking what it believes is a connection attempt (blocked by DOS protection).

I have personally seen this problem and have investigated this with NTL, however I was unable to resolve the problem with them.

This message that you are seeing should not be listed in the router and in fact the more entries like this the more that the connection speed will slow down.

Due to the fact that I have been unable to trace the route problem in the past I can only conclude that the firewall in the router is generating these errors incorrectly and is in fact causing the problem.

In order to resolve this issue please reply stating a full contact address including postal code and telephone number and I will arrange to replace this router.

Please accept my sincere apologies for any problems that this has caused."

So just waiting for a new router and i will see if it works.

Just posted this incase anyone has a simalar problem.

Re: Router problem trying to reach 20Mb speeds?
 

Belkin F5D7230 doesn't seem to do 20meg wireless broadband well in my experience. I got download speeds of 6-8meg (not significantly different to when I was on 10meg service) until I changed to a Linksys Wireless G router which gives me 16-18meg download speeds.

Re: Router problem trying to reach 20Mb speeds?
 

I think I have the answer on this one as I have the same issues with my ZyXEL cable router. What people are running into isn't a "port" speed issues but what was hinted at with the "NAT/Firewall" answer.

You have basically come up against the router's maximum throughput when the firewall is enabled, around 10mb/s if my ZyXEL is anything to go by.

What you must remember is the difference between “PORT� speed (10/100 baseT et al) and actual packet throughput, through the firewall, which is dependant on the CPU (generally RISK processors) in the router itself. I can only guess that when the specs where drawn up for these router the manufactures, which lets face it are probably only a handful, then the product gets branded a “Belkin� or a “Netgear� didn’t think Internet speed for household use would get above the 10mbs mark. Or as with many things for home use they are built to a price and/or a shelf life. That being said a lot of brand new routers on the shelf’s now are still limited to 10mbs with the NAT/firewall enabled.

I rang up ZyXEL customer support, very helpful chaps, they even rang me back as promised I nearly fainted LOL (not use to that kind of service being a Virgin customer). And they explained the above to me, Making sure I was running the latest firmware as well since they fix possible bugs which could hinder packet throughput. With some of the ZyXEL products on the main web admin page it now displays a CPU usage percent figure.

The two products they recommended which understandably are ZyXEL only:

http://www.zyxel.co.uk/web/product_f...5-4B2C83DFD32B

with a maximum throughput with firewall enabled of 25mbs.


In my opinion it may be better to buy a gigabit switch for the wired connections and then buy a wireless router for the WiFi access point and firewall, then connect the switch to that. Unless anyone knows of a better way I am all ears.

Re: Router problem trying to reach 20Mb speeds?
 

Look here- http://www.virginmedia.com/help/20mb...timisation.php

My Belkin was limited to 10Mbps until I followed these instructions now getting 14Mbps average just waiting for a replacement for my SB4100 to see if I can get 20Mbps.

I think at least half the people stuck at 10Mbps would see great improvement after following this guide.
