Laptop ethernet controller

I am connected to internet through LAN, which is 100 Mbps. My internet speed must be 35 Mbit/s inside my country, which i reached when used my desktop. Since i bought my laptop, i have 1 Gbps ethernet controller Marvell yukon. So now my speed is only 10 Mbit/s. I guess this must be some compatibility issue with switch to what i am connected. In ethernet controller settings i have autonegotiation mode, but that doesn't seem to help. I've changed settings to 10/100 half and full duplex but then speed decreased even more.
My provider doesn't give any response to this.

Is there anything i can do?

 

Have you verified your download speed, using a tool like Speedtest.net?

 

That is right. I got the information from speed measuring site located in my country and the info is very reliable, as it is core backbone provider. I've been getting my 35 Mbit/s from there, now i get 10 Mbit/s.

 

What is your ISP plan?

 

That is not the point. I must have 35 Mbit/s and my provider say i have this speed. I have had it previously without interuption. At the moment my speed stops at 10 Mbps. It never goes up, however it should. The problem, and i am more than sure is with my gigabit ethernet card. I just want to know if there is some workaround.

 

You said the speed was 35Mbps inside your "country", which didn't make much sense.

Well, if you are paying for 35Mbps, then you better find the reason for the speed decrease, which could be in your end as much on the ISP end.

Now, it looks like you have a desktop and a laptop, are they both getting 10Mbps ISP throughput?

 

It makes a lot of sense. I get 35 Mbps inside my country, i get 10 Mbps when using foreign traffic. I used local speedtest site, to check my connection speed. It shows no more than 10 Mbps. On my desktop i get 35 Mbps. My desktop is disconnected, i use only laptop, so they don't share anything.

 

Do you have the latest drivers for your laptop? Have you contacted the laptop manufacturer about the speed issue?

 

well, i've the latest that are available. i don't think it has to do something with laptop. ethernet card itself works good. i believe it is compatibility issue with that 100 Mbps switches cannot correctly handle with gigabit ethernet cards. i just thought maybe someone has experienced something similar.

 

I haven't had any problems with my gigabit cards working with 100mbps switches. Can you connect your desktop and transfer some large files between your machines?

Also, what OS do you have on the laptop?

 

I did connect my desktop to my laptop with ethernet cable. There were no problems when i transferred files through ethernet cable between laptop and desktop.
At the moment it is like - local speed goes precisely till 10 Mbps and not further. I've download large files from ftp testing servers, and i see how speed stops increasing, it just locks at one point. I am guessing that switch configuration/support is a problem, but i cannot prove it and provider is not even interested in that. I just installed latest Marvell Yukon drivers btw, and no changes.

Laptop has Vista home premium.

 

Did you do this with a crossover cable, or did you have the laptop and desktop connected to a router?

I recall reading someone with similar problems with Marvell Yukon and an ISP, but I don't know the link.

 

I did it with crossover.

 

Try connecting the two computers to your router, and then try to transfer files again.

 

I don't have a router. I am connected to internet directly through wired cable, that is connected to switch that is placed on the roof of my apartment. I'm in LAN.

 

Have you talked to the person who takes care of the switch? Do you know the manufacturer and model of the switch, and if it is a managed or unmanaged switch?

Do you have a firewall installed on the laptop? If so, have you tried disabling the firewall to see if it is causing the problem?

 

ISP takes care of the switch, they created and maintain LAN to which i am connected. I believe there is some incompatibility. I just ran Marvell Diagnostical tool and it showed everything is fine. I have no idea what is the switch model, only my ISP knows that, and they are not providing such info.

Yes i have firewall. Tried with and without, speed limit still is constant value. I had the same speed when i was on 10 Mbps router.

 

You should continue asking your ISP for assistance. If it is possible, and your laptop has either a PCMCIA or ExpressCard slot, you could buy either a 10/100 or 10/100/1000 card and see if you can connect and get faster download speeds. Other than that, I don't have any other ideas.

 

what type of wireless router or WAP are you using...brand name and model number???

Edit: opps missed the bit about the router...but i am still a little bit lost in reading the thread...unless i missed something else...do you have a modem...or just a cat5e cable coming into your place

 

The OP lives in an apartment building with a switch that supplies internet to all of the apartments. The computer is connected via ethernet cable.

 

That's right. My house consists of 36 flats. On the garret of our house there is a switch, to which i am directly connected via cat5, as mentioned. And it comes into my computer. I just want to think, that maybe there are switches that are not supportive to gigabit ethernet cards? And that they can give lowest speed possible.

 

May be someone has changed the settings of the main switch, in "auto sensing" switches will allow a mix of 10 and 100Mbps connections, the slower 10Mbps transfer won't slow down the faster 35Mbps or even 100Mbps.

 

There are such settings in switches?

 

Depending if it is an unmanaged or managed switch;

If it is a managed switch, then you can find the following typical features:

Turn some particular port range on or off
Link speed and duplex settings
Priority settings for ports
MAC filtering — and other types of "port security" features which prevent MAC flooding
Use of Spanning Tree Protocol
SNMP monitoring of device and link health
Port mirroring (also named: port monitoring, spanning port, SPAN port, roving analysis port, link mode port)
Link aggregation (also called: bonding/trunking)
VLAN settings
802.1X network access control



Ask the guys who is in charge of the telecom room about what type of switch is and explain your problem to him. My suspiction is that we have enable other users and that the switch is overshared.

 

invest in a wireless router...i would think that would solve your probs...and you can also move around your flat with your lappy...modern routers are designed to convert from one connection to another...and usually from 10-T and 10 and 100 Mbits/second networks without using crossover cables...smarter technology

Edit: if you go with a router...before configuring...using CMD...type in command ipconfig/all...this will give you all the info that you will need to set your router...write all the info down...i.e. IP Adress...Default Gateway...DHCP Server...Primary and Secondary DNS Servers
