Bandwidth control is not enabled.
No clashes with any IP and MAC among devices.
No binding done between IP and MAC.
IPv6 was already disabled.
DoS protection was enabled.

I disabled DoS protection and tried to download apps from Google Play Store. 4 apps were successfully downloaded, and internet was not disconnected. So could this be the reason? I would keep DoS protection disabled for few days and check. But is it recommended to disable DoS protection?
 
well, a lot of routers/modems don't have that. plus being behind NAT and bridged modem, there's already some DoS protection (sort of) - the modem will drop unsolicited pkts from wan interface.

if that's indeed the issue (easy to confirm - enable and see if anything gets added to DoS blocked host list), may be you could try increasing those limits. if it was play store, i'd think it was tcp syn flood (i have no idea why that tripped though). so increase that to 200/s may be. dropping ping from wan port should be no issue.
 
@hemant you were right. Issue was related to DoS protection. After I enabled DoS protection and ran App update from Google Play Store, MAC of my mobile was blocked in DoS protection, and internet stopped. After I cleared MAC from blocked list, internet started working again.
I would just disable tcp syn and check what happens.
Thanks a lot for identifying exact issue 👍🏻

another thing you could do is try transferring something between two local devices connected to the router - see what max speeds you hit. you can triangulate if it's cable fault or interface fault or router fault. if cables between your devices and router can hit full speeds, then may be it's LCO's splicing went bad or the cable had kinks.

its not the cables between my system and router coz problem is there on devices in wireless connection also

@SVK probably something to do with your phone then. Try looking at the wifi log.

Run a malware scan as well.

Another update from my side.
My Son said that some games were automatically getting installed on Tablet. I had set Parental Control ON and any app or game with 3+ age rating would need pin. Yet some games were getting installed automatically of 3 age rating. (I asked him if he was installing them, he said it were appearing automatically and he also played those. 1 game I remember is Bike Hop).
I scanned by Samsung's inbuilt security, but no threat was detected. I installed Malware Bytes and scanned by that, still nothing detected.
Finally I formatted Tablet, and guess what, after Tablet was restarted, it updated apps from Google Play Store without any disconnection even though DoS protection is enabled. Other Phones are also updating apps from Google Play Store without disconnection.
So it looks like issue with some Virus or Malware in Tablet which was causing issue.
Thanks for your valuable inputs @maverick27 @JB701 @Reklez @hemant

@Alpha018 It's a 100% packet loss . It also occurring to me nowadays . Getting bans for hours due to this bullshit network! The most irritating thing is it solves after 2-5mins automatically . Even assigned IP address is same . It must be a backend issue.
 

it's possible that's a fault in bsnl's network but it's also a symptom of cable kinks/splicing issues.

also if you guys have routers that have DoS protection stuff (apparently fairly standard in TP-Link these days), you should try disabling it.
