I run Ubuntu 12.04 dual boot with windows 7 on my Dell Inspiron N4110.My internet speed is very slow on my Ubuntu.My ethernet speed is 100 Mb/s.But,I am getting only 10 Mb/s.This is really annoying me.My laptop has Realtek RTL8111E Gigabit Ethernet Controller on board(found on dell website).I have googled it and found there are known issues with realtek RTL8111 ethernet card.I decided to download the driver from Realtek.
The output of lspci -v command
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05) Subsystem: Dell Device 04d7 Flags: bus master, fast devsel, latency 0, IRQ 46 I/O ports at 2000 [size=256] Memory at d0404000 (64-bit, prefetchable) [size=4K] Memory at d0400000 (64-bit, prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: r8169 Kernel modules: r8169
This output shows the network card is RTL8101E/RTL8102E PCI Express Fast Ethernet controller and In Windows,It is Realtek RTL8111E Gigabit Ethernet Controller.Are these both same.which one should I download.
I never had an issue with 11.10.... Help
