Deco S7 V1 Upload speed dropped severely after firmware upgrade
Deco S7 V1 Upload speed dropped severely after firmware upgrade
Hi @David-TP
I just purchased a deco S7 V1 (US VERSION) with the firmware:
1.4.1 Build 20230324 Rel. 50892
Then upgraded it to 1.5.2 Build 20240927 Rel. 68997 via the Deco app. However, right after all devices (3 phones 1 pc), the upload speeds dropped sharply, 60% on desktop and almost 90% on mobile phones.
I have a symmetric internet bandwidth of 110mbps, but the phone gets a maximum of 20 upload and pc gets 50/60mbps.
Before the upgrade everything was fantasic, and I was getting more than my allocated bandwidth speeds on the speed test results. So it's definitely the firmware.
I saw others are making the same complain on the forums about the upgrade. You recommended someone to download the old firmware via a link but the old firmware is not there.
Can you please share the file so I can downgrade. I spent quite a lot of money buying this router and this is not working for me.

Most ONU (Optical Network Unit) devices support bridge mode, which allows them to function as a pure fiber modem, passing the public IP address directly to a third-party router.
This mode is ideal for users wanting to use their own high-performance router to manage NAT, DHCP, and Wi-Fi
Putting the ONU is bridge mode shuts off it's ability to handle NAT, DHCP, and Wi-Fi and allows the deco to handle these things.
If the ONU isn't in bridge mode then both the ONU and deco are trying to handle NAT at the same time which can cause an issue know as Double NAT.
You can read more about Double NAT here
Your ONU may already have bridge mode turned it you would have to call them to see.
