WiFi connection issues

[cecil1989]

Hi Guys,

I am having an issue I hope that someone will be able to help me fix.

Basically, I am having a lot of trouble connecting to the internet via wifi. I've spent hours trying different troubleshooters etc but haven't had any luck.

Basically:
*It says its connected but with no internet
*Has done so on numerours routers, so pretty sure its the PC
*Network Adapter says its running fine
*Network and Internet troubleshooters have been run on windows 10
*Network adapter driver has been updated
*Flushed the DNS/cookies/cache/everything anything online has said to do
*It works using the same wifi accessed though my phone via a usb teather
*It seems to work okay when on public wifi and there is some sort os "sign in" page, but not for normal home networks? If that makes sense?
*Have tried disabling AVG antivirus

I have probably tried a million other things too, but really need it sorted so I can get some work done :/

Have you checked the network sharing, it may be blocking the internet access

[gemma10]

Have you tried using an ethernet cable?

[cecil1989]

It is working in my hotel now (has a pop up window to log in - so seems to work when it does this). But I will check the networking sharing/firewall if it happens again.

I didn't have access to an ethernet cable unfortunately.

I have generated a wlan report which indicates a heap of low connectivity or no network connectivity. I'm just not sure what I'm looking for on it to locate the errors shown on the report?

Could I clarify what is saying there is "low connectivity"?

Is the computer able to obtain an IP from the network or are you not even finding and connecting to the network?

To find out, hold down 'windows key + R' , then type in 'cmd', then 'ipconfig. I suggest you post a screenshot of the output.

I changed a couple of laptops to newer Intel AC wireless cards a while ago - one worked fine & the other was behaving in a similar manner to what you are describing. Messed about with drivers without any change & finally went back to the old wireless N card.

While searching for a solution to this I did note that there are some Intel AC drivers that are problematic & that reverting to an older driver often resolves issues.

Don't know if it applies in your case, but maybe helpful.

Try to connect with Ethernet cable. If it works fine then you have WiFi issue in your wireless card ,if not then open your router webpage by typing 192.168.1.1 to reconfigure your network otherwise contact your service provider to fix it.

Router ip addresses are normally 192.168.0.1, they do vary but try
ipconfig /all at the cmd prompt.
This will tell you your default gateway which is normally the router address.,

Also try downloading inssider, this will show wifi signal strength for all relevant SSID's.

Momoe,


Are you sure ? All my routers have been 192.168.1.1

[jimtherev]

I've had both *.*.1.1 and 0.1.
I've also had one which was .1.254 (heaven knows why!)

often something in the PC - we have a portable that varies from full connectvity to zero connectivity depending on which location it's in - worse sometimes it works in an office and the next time I visit it doesn't........................ tried dozens of fixes but no joy - the only guarantee is an ethernet cable

[crablab]

AVG has a nice piece of software that interferes with the network card at a very low level - you would need to fiddle around in the network card settings to disable it. (PM for detailed instructions!)

If there are any WiFi weirdnesses in Windows it is always worth deleting the stored Profile for the particular router SSID as a first step.


Open a command prompt - as administrator may be necessary depending on your setup.

Find the name of the SSID you want to delete the profile of and delete it. You will have to put the password in again.


e.g.

C:\Users\harry>netsh
netsh>wlan
netsh wlan>show profiles

Profiles on interface Wireless Network Connection:

Group policy profiles (read only)
---------------------------------
<None>

User profiles
-------------
All User Profile : iPhone
All User Profile : Huawei E5372s-32
All User Profile : AndroidAP
All User Profile : SKY97324

netsh wlan>delete profile name="Huawei E5372s-32"
Profile "Huawei E5372s-32-064" is deleted from interface "Wireless Network Connection".
netsh wlan>
netsh wlan>
netsh wlan>exit


C:\Users\harry>


You can alternatively type the whole netsh command as follows, but I seem to find the above method easier.

Whole command in one shot example.

C:\Users\harry>netsh wlan show profiles

Profiles on interface Wireless Network Connection:

Group policy profiles (read only)
---------------------------------
<None>

User profiles
-------------
All User Profile : iPhone
All User Profile : AndroidAP
All User Profile : SKY97324


C:\Users\harry>

Good luck.

The router's address can in principle be any valid IP address.

e.g. 1.1.1.1, 97.123.210.222, 8.8.8.8, .......,

A while back by convention people often used to use the last address in the network range for the router (default gateway), hence 192.168.1.254. The range is specified by some address in the range (ideally the zeroth one) and the netmask. The netmask specifies which address bits are "network" bits and which are "host" (or device if you like) bits.

More recently we seem to use the first one (above the zeroth). So ending in .1 is common.

I look after about 400 Huawei Mifi devices and they are either 192.168.1.1 for all except the latest model or 192.168.8.1 for the new one.


Of course if you chose 8.8.8.8 for your router you will most likely have some difficulty of communication with a particular google DNS server which is also 8.8.8.8. and possibly other devices on the 8.0.0.0 255.0.0.0 network too.

The "correct" (and sensible) thing to do is use a private address range: https://en.wikipedia.org/wiki/Private_network

Your ISP name and password correct?
