Over the past years , we have been encountering with this problem on our laptops.
The cause may not be always the same , this means you have to try different fixes for the same problem one by one if the problem continues.
1. Lets start with router. See if other devices gets connected with the router. If no,the problem is in the router itself. If yes , the problem lies with in your laptop.
Restart the router or the connection itself that will remove the cache and fix the network issues.
IF THE ROUER AND MODEM ARE SEPERATE,
turn both off
wait for 30 seconds
turn on the modem
wait for 1 minute
turn on the router
wait few minutes
check if the internet can be acessed now
2. Problem with connection
Check for broken cables , broken services etc. If the lights on the router is blinking or flickering this indicates a disrupted connection and you will have to contact your Internet service provider.
3.Device
Restart the device and see if the problem fixes.
If not,
Right click on network icon and trouble shoot
windows will attempt to automatically fix the connection issue by itself.
4. DNS cache conflict
to fix
press: Windows+R
type: ipconfig/flushdns
restart the computer now
5.Ip address
if 2 devices and same ip adress then conflict. our device is given a static ip address that's in DHCP range and same is assigned to another device connected especialy when our laptop goes in to sleep mode.
to fix
search : cmd prompt
select command prompt
enter: ipconfig/release
Enter: ipconfig/renew
Or
Type:ipconfig/ flushdns
Type: nbtstat - R
Type:nbtstat - RR
Type: netsh int ip reset c:\reset log.txt
Type:netsh winsock reset
Restart your computer
6. Outdated wireless mode
older devices have 802.11b or 802.11g where router 802.11ac (latest version and fastest)
doesn't gets access to. to identify this problem
click on network and sharing center
choose your network name
double click for details which gives you ip address
enter this ip address in the search url address
log in to router
look for wireless mode
click on wireless setting
change wireless mode to 802.11b
restart the computer
Thankyou
