Hi,

I am using HP laptop. I can connect to mobile hotspot from fedora 25. But it doesnot connect to NetGear wifi router. I have tried adding Google DSN 8.8.8.8 , 8.8.4.4 , but it didnot work. Please suggest a solution

So you can connect to the WiFi but the network configuration does not work for you? It would be helpful if you add the output of the following commands to your question. iwconfig, ip address and ip route.

Hi @thomaswood,

  1. I have a created hotspot in my android mobile, which am able to connect from my laptop(fedora)
  2. if I try to connect other wifi router, it doesnot connect. Mean time it will not reconnect to the above hotspot also. I need to reset edit hotspot and reset that connection in my lapatop. Then I can to hotspot again.

Am new to Linux and also first time I had installed this.

Using the Google DNS servers won't help you here for two reasons. First, your computer knows (or should know) the router's IP address and second, if you can't reach the Internet, you can't use anybody's servers. Try running traceroute 8.8.8.8 and see if you get a response from your router, and an eventual response from the server. (Getting * * * from some of the hops is OK.)

Looks like your WiFi card in your computer has some compatibility issues with the NetGear router. Without knowing the detailed specs about your router and WiFi adapter one could only guess. A good starting point would be to disable things like DraftN, WPS on the router. Try to change the frequency or set it to auto on your router and try to lower the transmit power of your router.

Finally I had fixed it..

This link was very useful. Before running these commands, wifi signal was very weak and was not stable connection. After running the below command, I hav started seeing actual signal strength as in my mobile wifi scan.

 1. modinfo -p rtl8723be
 2. sudo modprobe -r rtl8723be
 3. sudo modprobe rtl8723be ant_sel=1
 4. iwlist scan | egrep -i 'ssid|level'

Note: rtl8723be --> this is my wifi card of laptop. Search in google to find actual driver name as

yourdrivername linux

Hi,

Installing Fedora 25 on my HP laptop I also encountered the problem that WiFi did not work with the Realtek RTL18723BE card. The following solved the problem :

  1. Create a file 'wireless.conf' in '/etc/modprobe.d/' e.g. using 'sudo vi wireless.conf'
  2. Write the following line into it : blacklist acer_wmi
  3. Create a file 'rtl8723be.conf' in '/etc/modprobe.d/'
  4. Write the following line into it : options rtl8723be ant_sel=1
  5. Restart your laptop

Notes : I did also, as recommended in a forum, disable 'Secure Boot' in the BIOS. I there also disabled Bluetooth since I do not need it.

With kind regards

Lars
