Bypassing Excitel Router/ONT

Little Brief about the issues led to this -
My excitel router (PPC, attached image) started giving random issues, Wifi shows no internet access on connected devices but LAN works. Whenever I tried login in router admin interface, after few clicks UI just hangs and had to manually press power button and restart router. Tried raising many tickets, they did reset and created change device request, no response for 7days, then I reached Local operator for device change and he says excitel is not giving him any replacement router he only gets routers for new connection. Made a conference call with excitel customer support and LCO, same discussion happened, (we will transfer your call to partner support, hold for 2min and gets disconnected). Also tried mailing excitel support but same BS response. We will work on it blah blah, No solution.

I had an old TP Link Archer A9 flashed with OpenWRT, connected it to excitel router via lan and started using it as Access Point. But main excitel router again started to hang and drop pings, I also tried to connect with Tp-Link router as DHCP (tried to turn of wifi on excitel router and connected Tp-link with dhcp and enabled dhcp on tplink so it handles the routing, tried all possible ways to give minimal load to excitel, but no it doesnt solved the issue)

So, I decided to do a little search, after reading through post of many members on bypassing External ONT and using fibre directly by using personal ONT or with Routers that support ONT, I tried to give a try.

I had a Digisol DG-GR6010 in my home provided to me by previous provider (Siti Broadband).
Connected Yellow fibre cable to digisol, connected to admin of digisol via lan, gave PPPoE login but it was not authenticating, tried to find any option to change mac but there was no option, So connected lan from Digisol ONT to Tp-link, Opened LUCI UI of router (Tp-link is flashed with OpenWRT, but procedure is same for other routers too), Added WAN config and PPPoE details (attached screenshot) changed MAC to excitel router mac, Save, wait 15sec, Connected, Internet access.

Used this for 2 days, no issues, whatever data I am consuming is also not visible in Excitel App (So maybe it wont count in FUP), App shows Last Connection active 2Apr

But here comes the issue, I have 200mbps plan, when I am using Internet with Digisol ONT and Tplink router(OpenWRT), I get max speed of 180mbps, for both down up, like there is a capping, it never goes above 180mbps. Tried many sites. Tried disconnecting all devices cleaned connection ports, Never went above 180mbps max or even lower.
But when I connect fibre to excitel router and my tplink to excitel router lan and check speed, It shows 250mbps at start and comes down to 210 - 205 but never below 200.

So I need help, what I am missing, does full speed only work with operator provided router? So I will need to get a new connection if I need new router and forget about my old connection recharge balance.
Or is this an issue with my Digisol or Tplink PPPoE with WRT is capping the limit.

How shall I proceed to solve this....

Have you tried updating the firmware on the Digisol ONU?

Digisol Firmware

Also, double check if any QoS setting is enabled in OpenWRT. It might be capping max speed. Although it's unlikely if you are getting full speed when connected to LAN ports on the ISP provided router.

Sounds to me like QoS is enabled and working as intended. If it's not that then you can try using an older version of OpenWRT on your router and see if that solves it. (if it's not up to date then update to latest first).

Nope, I didnt. I checked the site for new firmware, but it shows DG-GR6010 Realtek and my ONU has only DG-GR6010 written in back, so I dont know if should upgrade this.

I did a reset once, i dont think QoS is enabled by default. Its running with latest version available for the router

Any chance the hardware revision is mentioned on a sticker on the unit or the box it came in? It might be mentioned in the configuration portal too.
 
Sticker shows Hardware vers A1
Yeah this may not be the Realtek one. I managed to find a couple of firmware files for what appears to be an older revision. Can you share a screenshot of the device info page on your web dashboard? I have attached two screen shots of the page from old and recent manuals of this model from Digisol.

upgraded to EPON ver V2801SG_IMG_V6.0.4P1T8-200710_Digisol_EPON
still the same issue
if anyone following this also does the upgrade, wait for 2min let the red green yellow light blink for 2-3 min and it will restart. then enter the new password

still the same issue
Open-WRT sometimes has reduced performance compared to native firmware as it uses open source drivers which do not support hardware acceleration for some stuff like NAT. Something along these lines might be happening when it's connected to an ONU directly instead of the ISP provided router.

If it's not too much of a hassle, Can you try reverting to stock firmware and test? Other than that, I can't think of anything else.

OpenWRT's PPPoE performance can be limited since it lacks hardware NAT acceleration found in stock firmware. Testing with the stock firmware might help confirm if that's the bottleneck.

did you try enabling hardware offloading under Firewall it might help
here comes my saviour, you just made my day and solved my 2months long headache
I first did soft offload and it improved speed drastically
then i tried hardware offloading and couldn't find difference but as you said I will keep hardware offloading on, I don't know the difference
Also, I would like to show speed I am getting in steam download, it went above 200 (note I hv 200mbps plan only) but I am now getting above 200mbps and by using old excitel router it never touched 200
thanks man, thanks to others and special thanks to @StygianClaw. You guys are just awesome.
