Hi all, I'm using OpenWrt on my Asus RT-N12+ B1 router from last month, recently I upgraded my internet plan from 50 mbps to 100 mbps and I'm seeing a very interesting thing that with OWrt I'm hardly able to touch 80 mbps and most of the time around 60 to 70 mbps ish speed where as on stock
i'm easily able to touch 90 mbps.
Now I've two questions
Firstly I already know that, tough the router brands advertises 300/450/600 mbps but it's only possible in wireless mode and the actual speed is limited to lan speed but how can this much variation is possible, can any one explain me?
More clearly why there is so much variation in speed in OWrt and stock? One more thing to say I've tested both firmware in 20Mhz and 40Mhz width to see if anything special happen but all testing went in vain
below are the screenshot for OWrt and Stock firmware mode speed test
Secondly one more thing to ask what is this MCS 7/15 and Short GI is all about? And on some of my device OWrt shows 72.2 Mbps and sometimes 144.4 Mbps what this difference is?
I know these limitations but I was asking just from curiosity that if I do use stock I can easily hit around 90 ish mbps speed where as in OWrt I'm reaching atmost 60-70 mbps which is around 80% of stock speed, that's why I was trying to ask why this many difference?
Coming to hardware I've experimented the same with my Archer A7 https://openwrt.org/toh/tp-link/archer_a7_v5#installation_using_the_tftp_method but still the results are almost same in 2.4Ghz single band, speed is reaching at most 75mbps
So why this much variation?
Thanks pal for the MCS and Short GI and coming to offloading I'd definitely give a try to see if any change happens or not, but in the stock firmware I've not found anything like SW/HW offloading in stock like in OWrt
