Weired PTCL Problem. Help needed.

[Curious_Guy]

i will try this too.. i did hard reset it started working fine for about 30 mins and then back to same problem.

- Change your wifi password.
- Restart your router.
- Connect 1 device at a time.
- Use it for 30 minutes before connecting another device.

When you say the same issue start occuring on the new router, my suspicion is that someone could be using your internet for malicious purposes - a device could be hacked, or have exploits making it part of a botnet - which is causing app servers to block you.

When an app blocks you, it doesn't block from the device, it blocks from your internet / IP.

Not sure if PTCL rotates IP on each router restart. If you can, check if your IP address changes after router restart. Simplest way is to simply type "My IP" in google. If it doesn't, call PTCL and ask them to assing a new IP to you.

There are 2 things that u need to do to diagnose the problem.
1. Reset the modem, That can be done with PTCL help.
2. Reset ur mobile, u should be able to do that.

IF after both these the problem still persists, then the issue is not at your end. You have to then force the PTCL to accept it as a setting/firewall issue on their side. But they usually don't accept the mistake in the start, You have to convince them.

Go to the router page, advanced settings, then DSL, make sure u select the option as in pic.

Hi
i know this might nt be the beat forum to ask this question, but i have seen many tech savy members so here it is

i have PTCL DSL connection (can't have any other as no good service available in area, 4g devices become to expensive)

those of you who know normally 3 lights should be present on router & internet light blinking & in my case it is so.

but mobile wifi says connected but no internet but if i go to chrome i can visit sites play videos in 1080p but none of the apps work, youtube whatsapp Fb etc none in app but can visit these in chrome.
i hope i have explained my query

PTCL man is also helpless in this regard

edit - it was working fine 1 week back then suddenly this started happening, have already changed & reconfigured the router. it started working on apps for 15 mins then back to same problem

any help from you guys?

Hi, I feel your pain, before I continue, just a quick question: Are you able to use the broadband when you connect a PC or Laptop using an ethernet cable directly to the router? If so I think I know what the problem is and may be able to help you.

STEP 1: ROUTER LOCATION
Router location: Before we being, you have tested a hardwired connection into your router by connecting a desktop pc or laptop directly to your router and you are able to access the internet without any issues, the next step in diagnostics for WLAN connection is router location.

The Wireless router is a weak and fragile create, like most radio waves 802.11 is a delicate flower and doesn't like much interference from its surroundings such as the router being next to the television, microwaves, on top of a fridge, a glass table, in a cupboard, next to a window etc, in tech speak this is known as RIEN: Repetitive Electrical Impulse Noise.

This diagram will help you understand:

Another thing you need to be very careful about with regards to wifi routers is: Never place them next to an extension plug/lead as these are not shielded and leak electrical impulse noise which interferes the signal, the next device you should not have next to your router is a cordless telephone as it runs on the same 802.11 frequency and any AM/FM radio.

So now that you have checked your router location and you are comfrotable that there is no device interfering with the signals from the router and the router is placed in a open, clear space without obstructions, we can move onto the next step.

STEP 2: Wireless Diganotics
1. Find out what router you are using (this is important to continue with troubleshooting)
3. Keep your devices connected to your router wirelessly (do not disconnect them)
4. Now on your pc run Command Prompt as admin (Black DOS Screen)

5. And you will need to type in: netsh wlan show all

It will run and a lot of text will come up on the screen, don't worry, find your devices on the list, most importantly find your router and check for the following:
It will be something like:
SSID 1: PTCL or DLINK etc
Check which radio type you are on: is it 802.11ac or N? (This is important)
Check what channel it is on i.e: Channel 1/9/11 etc

6. Next in the command prompt (black screen) type in the command:
netsh wlan show networks mode=bssid

This will show you a list of all the wireless routers around you i.e your, your neighbours etc. You are looking to find your router for example SSID 1: PTCL/DLINK etc

A. Check the channel your router is on and what signal strength it has
B. Check your neighbours routers are they on the same channel (for example if your router is on channel 1 is your neighbours router also on channel 1?)

Scenario 1: Channel Co/location/ overlapping
If your router and neighbours router are on the same channel you will be experiencing bandwidth congestion, this can be resolved very easily and this is why you need to know your router make/model to access it's admin portal, normally this can be done by typing 192.168.0.1 or a similar IP which should be on the back of your router.

The username is normally admin and the password is also admin but check your user manual, if you don't have the manual, you can visit this website which is a emulator : https://www.chasms.com/#
Click on network > router emulator > select your router make/model and follow the on screen instructions to change the channel.

For this example I am going to use my router which is a TP LINK as an example for your ease, the IP address to access my router's admin page is 192.168.0.1 in the address bar and you will be met with this screen:

To log in to the router you will need the default username and password which is normally admin and admin or admin and password etc, you can find this information online.

When you log into your router, you will have a page very similar to this, you need to find the Wireless/WLAN tab and click on it.

Changing the channel on your router: You will see that your router's channel will be set on Auto, this is factory default and AUTO select normally makes the router use Channel 1, 6 or 11 and you will see when you run the netsh wlan show networks mode=bssid command, your neighbours router will also be on the same channel.

Change your router to Channel 9 for starters and press save.

Further diagnostics:
Now go back on your phone and download an app called Wifi Analyzer from the google play store, its free:
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en_GB

Make sure your mobile data on your phone is turned off and launch wifi analyzer, this app will allow you to see the wireless signal strength of your router in each room as well as provide a graph to see if your neighbouring routers are called interference/overlapping and also if you have any wireless deadspots in your house.

Here is a basic video on how to use the app:

Scenario 2:
You have tried the above, your mobile phone/tablet is connected to the router and your mobile data is off but you still can't access the internet.

Launch the settings tab on your phone, click on wifi settings, find your wifi connection, click on it, then click on the option to "FORGET". Now restart your mobile phone, and reconnect to the router, this will force the phone to request a new IP from the routers internal IP table and should resolve the issue.

Let me know if this helps...

That was super-detailed. However, I don't think these configurations are his issue.

On his phones, chrome works - other apps don't.
He changed his router, everything worked for 15 minutes, then went back to same state.

I think something might be sending out too many / malicious requests resulting in his IP getting blocked upon detection by app servers. I'm reaching, but it's an odd situation.

If it don't work, try stormfiber

if that’s the case he can run a local trace on his router through wire shark. It’s a free packet analyser available online and this page shows you how to set up a capture on your router:

Hi
i know this might nt be the beat forum to ask this question, but i have seen many tech savy members so here it is

i have PTCL DSL connection (can't have any other as no good service available in area, 4g devices become to expensive)

those of you who know normally 3 lights should be present on router & internet light blinking & in my case it is so.

but mobile wifi says connected but no internet but if i go to chrome i can visit sites play videos in 1080p but none of the apps work, youtube whatsapp Fb etc none in app but can visit these in chrome.
i hope i have explained my query

PTCL man is also helpless in this regard

edit - it was working fine 1 week back then suddenly this started happening, have already changed & reconfigured the router. it started working on apps for 15 mins then back to same problem

any help from you guys?

Change WIFI Security type WPA, WEP, WPA2 .In sha Allah will solve your problem

Change your DNS to Google's (8.8.8.8) in your router.
Disable proxy settings from your internet explorer. (Internet Options).

 

[Evil Flare]

Disconnect the PTCL connection .. and go for local fiber cable connection ..
