Internet connection is slow behind router

Hello!
My internet connection is 16MBps from Comcast.  When I connect my pc directly to the Modem, the speed is 16Mbps.  If I connect the wired Linksys router Model: BEFSR41  V.2.0  to the Modem, and connect the other computer to the router, the internet speed goes down to 6Mbps.  The firmware seems to be up to date and all cables are in good condition.
I need help to get the internet speed up to normal while plugged into the router.
Thank you

Hi,

What is the speed of ports of  your Linksys router?
0
 
nishvCommented:
There might be some sort of QoS setting or a bandwidth setting may be throttling it...

Did you try factory restoring the router?

KvChaosCommented:
What do you mean by your internet speed?
When you connect locally using a LAN cable, it should give you a 100MB speed.

uetian, how do i find the port speeds?
nishv, how do i manipulate the QoS settings, or resetting the router to factory settings?  (Please note that I havent changed any settings in the router)
KvChaos, by 'internet speed' I mean that I pay for the 16Mbps package and I get that through the Modem, but it goes down to 6Mbps when i connect the Modem to the Router and my pc to the router instead of directly to the Modem.

Is this a managed Linksys Router?

Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
I dont think so but I am not sure what "managed" means, either, sorry.

RPPreacherCommented:
uetian is right.  This is usually a port speed/duplex mismatch.  Your router and modem need to have the same port speed and duplex.

MereteCommented:
To add do you have a line filter also installed between the phone and the router?
Also what are you doing here>> If I connect the wired Linksys router  to the Modem. <<
Just connect all the computers via ethernet cable to the router How many ports on the router?
Does it support more than 2 computers?

This modem is an 'voip' modem so a phone line goes right to the wall, from the modem.  If I connect a pc to the modem, I get the right speed, and if I connect a pc to the router which is wired to the modem, the speed is cut at least in half.

Seriously man... have you bothered to check this yet?

Sorry RPPreacher, I dont know how to.

RPPreacherCommented:
Log into the Comcast modem.  Check the port speed and duplex.
Log into the Linksys modem.  Do the same.

They need to match exactly.

If you do not have access to the Comcast modem, call Comcast, ask them what speed/duplex you should be using.

The Comcast support tech said he's never heard of a Modem port speed or duplex speed.  (4.28.09 @ 10:28 pm)  He also said that if I am trying to change speed inside the router, I am 'going in the wrong direction'.

You shouldn't put too much trust in those "support".. >.>
After all those "assistance" from that "support" did he prove to be even a little help?

I for 1 do not know how you manage to check that your internet speed has gone down to 6 MB.
If you're talking about your Local Area Connection speed, a wired connection should be either 10/100/1000. How did you get a 6 MB speed anyway?

Since routers are reasonably cheap. Do a search and read reviews.  I would replace it.

Crud.  I was afraid of that.  Ok, let me look at some units and I will get a new router and get back with you guys.  
If anyone has any recommendations, by all means post them here.
I will get back with you all shortly.....  Please stand by.

Merete, do I need a voip Router though?  My phone line goes from the Modem to the wall and doesnt go to the Router.  Thank you!!  Mark88

MereteCommented:
I am only going on what you have said Mark88,
Modem router, router same thing aren't they?
You probably don't need to buy another
basically your connecting Voip modem router to another router and the clients are connected to the router and has to pass through that router to the Voip modem.
So it's probably only a wrong setting or ip address
See if this can assist you
Setting-Up a Linksys VOIP Router Using DSL Internet Service
Extract
Most DSL providers use Point-to-Point Protocol over Ethernet (PPPoE) to establish Internet connections for end-users. To set up a Linksys router, you need to enable PPPoE on the router's web-based setup page.

Does your telephone go through this router also ??

Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
I know....Im trying to improve my written explanations here.  Sorry for the confusion.  I hope you all can bear with me.
The Comcast Modem is where the phone line comes from and goes to the phone jack in the wall (RJ11).
The Linksys router is just a plain, four - port router from about 2000.  And it has two pc's plugged into it.
The Linksys router and the Comcast modem are connected by one network cable (RJ45).

TonyStCommented:
I was just trying to understand why you are using a voip router when you are not using it for telephone as well as internet.  Routers with Voip capability employ QoS  (quality of service)  stuff.  Thats so the voice portion (phone) takes priority over the internet (surfing).  While I'm not sure this has anything to do with your problem this model router is a known DOG by all the bad reviews it has on good.  I would just replace it with a good old 10/100 router from Netgear (about $45.00) and be done with it.

Hi TonyST, we do use the voip phone service with Comcast.  
Cool, we will get a Netgear then.
Stand by.....

nishvCommented:
Mark88: QoS setting differs between routers and you need to follow the router's manual for that.

As for restoring the router, the reason I suggested cos I thought you might have tampered with QoS and it might be causing the issue.

nishvCommented:
After further investigation, I have found out that your router has a CAP on the firmware.

What is your Firmware version? Anything before 1.39 will CAP your router to 6 MPBS...

Try the latest firmware from Linksys...

Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Hi nishv:
I updated the firmware several years ago to the latest version.  I went to linksys.com to check again just now, and the newest one is still from 2004.  The file name is: Ver.1.46.2, befsr-v1.46.02_FW_code.bin.
I dont see anything newer on the site.
I used the router's 192.168.1.1 site help wizard to upgrade the firmware.  Then, I restarted everything and tested the speed again and it still only goes to 6-7.8 Mbps.
The router interface says the firmware is at Ver.1.46.2.

nishvCommented:
I am 99.99% sure it is a firmware limitation.

It is fairly old router and at that time there wasn't many net connections above 6 MBps, then they tweeked the firmware to give a bit more throughput to around 7100Kbps (7Mbps)...

The reason this router did not get many Firmware update is due to the onboad memory...

I have reason to believe it must be the firmware. You can try Open Source Firmware for this router but I can't seem to recall any for that.

I would recommend you check out Open Source Firmwares for it but yet again, due to the onboad memory size, I doubt anyone would have released one... But I might be wrong on that.

Hope it helps.

Excellent insight and thinking on this, nishv.  It appears that simply getting a new router, say an inexpensive netgear might be the best choice.  This router is 10 years old.
Do you agree/disagree?
Mark88
0
 
nishvCommented:
Getting an inexpensive router is definitely the alternative. You can get a Netgear or a Linksys, I personally would go for Linksys because of personal preference and experience along with Cisco gears...

If you are going to buy a second hand router, I would recommend you get a Linksys WRT54G because you can do a lot of tweaking on that...

I would recommend you get a router with Wi-Fi support because you will be using it at one point.

Hope it helps and if you need further help, do post your reply.

Do I need any special type of Router that "goes with" this existing Comcast voip Modem?
0
 
nishvCommented:
Not really, since BEFSR41 handles it, I don't think you need any special type of router. You Just need a DSL/Cable Router. _NOT_ a DSL/MODEM Router.
