Archer A5 AC1200 Causing ping spikes or even packet loss
Hello everyone,
I am kinda desperate already due to problems I have with this router.
Setup:
I've bought a device in a legit store (I am from Ukraine) and use it with my internet provider as a wifi router.
I've set up two networks - 2.4 & 5 GHz respectively.
We have like 5 mobile devices connected (all to 5Ghz spot) and 4 laptops (two to 2.4 and two to 5 GHz).
Problem:
It all first started with lags while watching movie and this followed 2.4GHz spot.
I've made a ping toward google.com - it all seemed right.
Whenever a packet loss between a device and router occur - 5GHz spot faces the same issue.
Like the 2.4 GHz is causing all of this.
Now it all got worse: my kid has online classes due to lockdown - and he just can't attend it normally as he constantly gets disconnects! (2.4GHz spot).
While writing this I've switched my MBP to 2.4 spot and I am shocked with ping 192.168.0.1 being this:
--- 192.168.0.1 ping statistics ---
457 packets transmitted, 457 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.733/13.969/747.780/58.172 ms
And this is a ping from MBP on 5GHz spot:
--- 192.168.0.1 ping statistics ---
20 packets transmitted, 20 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.915/95.365/342.612/108.738 ms
And this is - I am sitting just next to the router.
Diagnostics:
I've yesterday updated the firmware of device from stock to new one (2020 dated). It fixed things a bit, but not that issue is gone.
- changed the 2.4GHz to BG only (instead of BGN).
- disabled WPS
- pinged google.com using wifi router to see how router interacts with web - no packet loss for 50 packets nor the ping spikes.
- checked the wifi channels and selected the most less propagated one.
I need your help. This problems are ridiculous. Thanks
Update: Tried reducing the signal strength from "High" to "Medium" for both 2.4&5GHz respectively - not a fix either.
