Realtek rtl8192se wifi running slow after new router installation in Fedora
 
Hello,

I apologize if this has been covered, but I am having connection issues so searching is painful. Also, please let me apologize now for the wall of text that follows, I am trying to include as much info as possible up front.

I used Ubuntu for about a year, and never had any issues, but I recently had new internet installed, and ever since my wifi connection has been slow and unreliable (changed from DSL to Cable). Other devices on the network function properly (xbox, 2 phones, a different laptop) but mine does not. While trying to solve the issue, I changed my OS to Fedora (not realizing until later that it was basically the same thing).

I never had any issues with Ubuntu, and never really did any work with it. I strictly do email/internet on this computer, so it never really came up. I am a total newbie here.

I went to realtek's website, and downloaded the driver it says I need (LINUX driver for kernel 2.6.x and 2.4.x (Support x86 and x64) version 8.028.00)

I did an lsmod command in terminal, and this is what I get:

After downloading the driver from Realtek, I opened the file and clicked on the autorun. This is what I get when I do that:




#!/bin/sh

# invoke insmod with all arguments we got
# and use a pathname, as insmod doesn't look in . by default

TARGET_PATH=$(find /lib/modules/$(uname -r)/kernel/drivers/net -name realtek -type d)

echo
echo "Check old driver and unload it."
check=`lsmod | grep r8169`
if [ "$check" != "" ]; then
echo "rmmod r8169"
/sbin/rmmod r8169
fi

check=`lsmod | grep r8168`
if [ "$check" != "" ]; then
echo "rmmod r8168"

if [ "$module" = "" ]; then
echo "No driver exists!!!"
exit 1
elif [ "$module" != "r8169" ]; then
if test -e $TARGET_PATH/r8169.ko ; then
echo "Backup r8169.ko"
if test -e $TARGET_PATH/r8169.bak ; then
i=0
while test -e $TARGET_PATH/r8169.bak$i
do
i=$(($i+1))
done
echo "rename r8169.ko to r8169.bak$i"
mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i
else
echo "rename r8169.ko to r8169.bak"
mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak
fi
fi
fi

echo "DEPMOD $(uname -r)"
depmod `uname -r`
echo "load module $module"
modprobe $module

is_update_initramfs=n
distrib_list="ubuntu debian"

if [ -r /etc/debian_version ]; then
is_update_initramfs=y
elif [ -r /etc/lsb-release ]; then
for distrib in $distrib_list
do
/bin/grep -i "$distrib" /etc/lsb-release 2>&1 /dev/null && \
is_update_initramfs=y && break
done
fi

if [ "$is_update_initramfs" = "y" ]; then
if which update-initramfs >/dev/null ; then
echo "Updating initramfs. Please wait."
update-initramfs -u -k $(uname -r)
else
echo "update-initramfs: command not found"
exit 1
fi
fi

echo "Completed."
exit 0






But the command not found part makes it look like it isn't installing properly, and my connection is still very slow.

Any suggestions? Any other information needed? Do I just need to buy a different network card? Thanks!

I forgot to mention in my OP that the problem is intermittent. When it runs, it blazes along. I have yet to determine what causes it to slow down or speed up. Restarting/logging in/out does not seem to effect it.

Thanks!

I apologize if I am missing some sort of etiquette or protocol that will elicit a response.

If there is something I need to change or add to my post, please let me know.

Or is it that I am SOL?

Thanks!
