Good morning
i try to download my program again
its download about 1Gb then wifi drop two times from 1 G to 1.1 G !!
Okay I take it Mint is now reinstalled, and you have already applied these 2 fixes and rebooted:
echo "options rtl8723be fwlps=0 ips=0"| sudo tee /etc/modprobe.d/rtl8723be.conf
and
echo "options iwlwifi 11n_disable=1"| sudo tee /etc/modprobe.d/iwlwifi-opt.conf
Am i correct ?
If so, can you post the output from:
dpkg -l | grep network-manager
and
sudo apt-get install -s wicd
i’m sorry my friend , i bothering you even in weekend…

That’s not a problem Hayder, I wouldn’t be here if I didn’t want to be 
Anyway, open a terminal and run these commands in sequence:
sudo rm /etc/modprobe.d/iwlwifi-opt.conf
then
mkdir ~/networkmanager-backup
then
cd ~/networkmanager-backup
then
apt-get download network-manager network-manager-gnome network-manager-openvpn network-manager-openvpn-gnome network-manager-pptp network-manager-pptp-gnome
(be sure to get all that last command … it may scroll off screen on this forum)
okay, that’s a backup of the packages we’d need to reinstall network-manager if we find you can’t connect via wicd.
Now to install wicd, and uninstall network-manager … run:
sudo apt-get install wicd
then
sudo apt-get remove network-manager network-manager-gnome network-manager-openvpn network-manager-openvpn-gnome network-manager-pptp network-manager-pptp-gnome
(be sure to get all that last command … it may scroll off screen on this forum)
once that’s done REBOOT. ← IMPORTANT (but see note at the bottom of this posting)
When you reboot, you should see wicd on your panel where networkmanager used to be … click it, select your network from the list, and click “connect” … it’ll probably say it requires a key and throw u a window where you change to “wpa 1/2 (passphrase)” and enter your key … click OK and click “connect again” … you’ll probably also see a box for “connect automatically”, tick that too.
you should be connected … so test the stability of the connection
To UNDO
Instructions for if things go wrong, and you need to get back to networkmanager instead
Open a terminal and run:
cd ~/networkmanager-backup
then
sudo dpkg -i *.deb
then
sudo apt-get remove wicd wicd-gtk wicd-daemon python-wicd
then REBOOT
wicd should be gone, and networkmanager back
NOTE:- If the reboot hangs, the correct way to reboot without damage to the file system is to hold Ctrl+Alt+PrtSc, and whilst holding them type r e i s u b in sequence.
PrtSc is often marked as SysReq
and on some laptops it needs to be Ctrl+AltGR+PrtSc whilst typing r e i s u b
It’s also a good idea to leave a second or two between the reisub keystrokes.
its way better, but still there is disconnect but it connect automatically few seconds…
if the problem in wifi driver how can i know if there is new driver available and how can i install it?
There is a newer driver, but we tried compiling it previously and though it compiled/installed when we tried to remove it your system crashed.
I’m not even convinced this is a driver issue as the driver remains the same whether you use networkmanager or wicd … I’m wondering if it’s as much a router issue.
Did you change channel in the router ?
Have you tried switching to AES instead of TKIP or vice versa … or setting the router to B/G rather than B/G/N (I’d probably try this first)
my router is very simple without any Advanced Control , Tenda F300 , so i cant change the channel or change the security, just put password and thats it.
but it was working great on windows and also now work great on ipad iphone and chromecast
See page 13 here:
As you can see in the image, you should be able to change channel ( I’d suggest 4 or 8 )
You can also change the “Network Mode:” from 11b/g/n ( mixed mode ) … hopefully to either b/g or just g … in other words disabling “n” but leaving “g” enabled.
thats strange !!!
i dont have these menu in my router
also i want to upgrade the firmware , they said the the last software is 5.07 but in my router the firmware is 6.0 … chines product
but i notice when i leave my pc for some times and use the net the wifi is drop for a while !!!
So there’s no “Advanced” option if you log into your routers web interface ?
yes
for your info i use ppoe
So if you click “Advanced”, do you now see a menu down the left hand side like this
and are any of the things listed in that menu “Wireless” or similar ?
or maybe the channel settings are under the “Wireless” tab at the top
I cant read that image … but there must be a place to change the wireless settings.
do you know how to access your routers web interface by entering your routers IP address in your web browser to change settings ?
yes because there is no other way to access the router
192.168.0.1
Wow, that’s a weird router :o
I’ve never seen one that doesn’t allow you to change the channel
its ok now my friend, it drop for few seconds
my be there is update in the way
appreciate your kindly help
your the best
