High ping and latency issue.
Recently upgraded my router from tp link TL-WR840N to Archer C6 v3.20, my main purpose of getting dual band router was to get low ping spikes and latency as I play a lot of online multiplayer games that includes COD mobile on my iPhone 11 Pro Max, and the older router used to deliver ping spikes and frequent disconnections, after the upgrade the new router was giving even more ping spikes and disconnections than the older one, my ping usually stays around 80 with frequent spikes every min or two that goes around 150ms or so and disconnections. As I was not getting desired performance tried tweaking my router settings as follows:-
The firmware is up to date with version 1.0.5 Build 20201117 rel.41066
ISP: Youbroadband
Connection type: Cable
Plan: 75mbps
Location: Surat, Gujarat.
2.4ghz band:
Switched to best suitable channel using wifi analyzer.
Changed the mode to 802.11n only.
Channel width to 20MHz
Transmit power: high
5ghz
Mode:802.11 n/ac mixed
Channel width: 40MHz
Channel is set to auto
Enabled multi-user MIMO
Enabled QoS and gave priority to my iPhone.
Mesh network and IPv6 are turned off.
Changed the DNS settings from automatically to Cloudfare's public DNS server.
Primary - 1.1.1.1
Secondary - 1.0.0.1
Did everything, tried on other mobile devices as well but the performance has not improved a bit, the game is unplayable now. The old router used to deliver a ping of 30 to 40ms with ping hikes every 8 to 10mins.
Even tried to use VPN and 1.1.1.1 application to get connected with nearby severs but in vain.
Alongside the said issue there is one more, whenever i manually switch from 2.4MHz to 5MHz or vice versa the later connected network shows no Internet connection, need to turn off wifi network on devices wait for some time turn it on and than it gets connected.
Any help or solution will be highly appreciated.
