Dell 7720 ethernet 10Mbps only

Question

I have a Dell 7720 machine and the Realtek ethernet has only 10Mbps speed, i tried a few driver but the card has only 10Mbps speed on Windows 7. If i try the same cable (Cat6) with the desktop machine what is have the same OS, is working on gigabit, so the cable and the router is fine. And another network issue is the integrated Centrion 2230 is only working at 72Mbps, and the intel says : '802.11bgn, 2x2, dual stream delivers up to 300 Mbps speed and greater range and reliability. Energy efficient 2 for greater mobility and convenience.' Here is the link: http://www.intel.com/content/www/us/en/wireless-products/centrino-wireless-n-2230.html So this Dell 7720 has serious network problem. I will test the another Dell laptop i have 7110 and check if it is have the same problems or not.

Hi DELL-Senthil S, Meanwhile i figured out, that in the device properties i need to disable the energy efficient ethernet option. With this disabled the ethernet has 100Mbps. Thanks for the help.

Hi Warloxk,

Please try using the laptop in a different network (friends place or neighbours place) incase the issue persists with the different network, Please update the BIOS using the link below.

Connect the Ac Adapter while updating the BIOS and do not use the system until it restarts after the update

To update the BIOS please refer to the video in the link below.

After updating the BIOS incase the issue persists, you may have to perform a PC restore (factory default) settings using the link below.

Note: Performing PC restore will lead to data loss, so please back up all the files and folders.

Let me know about the progress.

Hi DELL-Senthil S,

Thanks for the info, i tried on a different network with different router (TP-Link) with different cables but nothing still 10Mbps.

Then i updated the BIOS from 12 to 15 and tried again, but nothing changed, then i reinstalled the realtek driver but still 10Mbps

The Realtek driver i installed : http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/inspiron-17r-se-7720?driverId=P7W53&osCode=W764&fileId=3126810682&languageCode=EN&categoryId=NI

The same cable with a Dell 7110 laptop has 100Mbps so the cable/router is fine.
