speed & duplex

[adora_9015]

i bought router dgn1000v3 it works well in wifi but when i connect pc or laptop with cable the pc get unplugged cable but the cable already connected when i searched about this problem i found the solution in speed & duplex option in net card properties advanced must changed to 10 mb full duplex.

my question : is there any option in the router to make speed & duplex work with option auto Negotiation not only 10 mb full?

thanks

Your network card(NIC) has a advanced setting section on their driver. If you OS is wondows from device manager >> right click NIC

card >> click property >> advanced setting >> there you will see it.

i know where can i find it im asking about speed & duplex option when i connect a cable from router to my computer it must be 10 mb full

if i choose 100 mb or auto option it never work and get unplugged cable

i need it to work with 100 mb or auto option

is there any way to do this?

The ports on the router are auto-sensing.  Your Ethernet cable may be bad.  Try a different one.

That is the problem with the ADSL modem. Not your NIC. Deal with it with your ISP then. Knowing it how come you raise a question?

What is your modem specs.? Ca it handle 1oombps speed?

[adora_9015]

i tried many cables the same problem

[adora_9015]

What's the model of your Ethernet card?

[adora_9015]

Realtek PCIe FE Family Controller in laptop dell 5520

and atheros ar8151 pci-e gigabit in pc

but they was work well before this problem happened when i bought netgear router

I think you are asking too much from the ADSL2+ modem. Typical sync. 'd speed of ADSL

modem is ~10mbps and I saw peak at somehing like 25mbps.

[adora_9015]

sorry cant understand

[TheEther]

It sounds like the Ethernet ports on the router are broken if they only sync at 10 Mbps.  Maybe you can try inserting a switch between the router and your computers and see if that helps.  Otherwise, return the router.

[adora_9015]

now i inserting a switch between the router and computers and the same problem

[adora_9015]

there is one pc works with auto option in speed & duplex, the main pc with router

[TheEther]

Your messages are unclear.  First you said you have the same problem when inserting a switch.  Then you said the main PC works.  Which is correct?

[adora_9015]

the person who has the internet service in his line phone, his computer works with auto option,

any computer else only work with 10mb full duplex

[TheEther]

Sorry, it's still unclear.  Is the computer that works with auto negotation plugged into a switch or directly into the router?

The other computers that only work at 10 Mbps are also plugged into the switch or are they still plugged directly into the router?

[adora_9015]

the computer that works directly plugged into the router

The other computers that only work at 10 Mbps i plugged them into a switch and directly into the router but the same result

[VE6CGX]

Can't understand? Then I suggest you to read Wikipedia on ADSL2+ modem to get

familiarize yourself with the said subject. I think your ISP is playing dumb to ignore

your question or concern.

[TheEther]

If the computers only work at 10 Mbps while plugged into the switch, then the router is not the problem. There's something wrong with the computers.

[VE6CGX]

Auto option is not important in this case. Either way it must be capped at 10mbps from ISP, then auto option is throttling down to 10mbps. It becomes non-issue. It is impossible to obtain 100mbps speed from 10mbps line.

i tried my laptop with both switch and router and got the same problem

but if you know where is the problem in computers tell me
