SSL protocol error after upgrading to 20230608.
I need to refresh every page two times to get rid of this nonsense. Every website. On iPad the App Store does not work anymore. It all worked fine before I did the firmware upgrade.
Tried to downgrade but I'm not allowed to do that. 'Upgrade failed. Please select the latest version of firmware to upgrade.'

Please refer to the following suggestions to see whether they could help:

@David-TP, Hi David, the experience with Deco M5 V3.2 with firmware 1.7.1 Build 20230608 Rel. 74023 is bad and unusable.
Could you tell me how to downgrade to an earlier firmware version. I will send the email tomorrow.
What I tried and did not solve the issue:
- Connected new devices, tried old devices and forget and added it again.
- iPad WiFi 2022 with iPad OS 16.5.1
- iPad Air 2022 iOS 12.5.7
- OnePlus 5 LOS Android 13 TQ2A.230505
- Samsung S21 FE 5G (SM-G990B) Android 13, 1 June 2023.
- I have tried to reboot the network.
- Set manual DNS of 1.1.1.1 and 1.0.0.0.1.
- Have two different internet providers, tried both and did a deco reboot.
Sometimes I get the SSL issue and sometimes the connection is so slow the pages times out.
This site can’t provide a secure connection www(dot)omroepbrabant(dot)nl sent an invalid response.
Try running Windows Network Diagnostics.

After some reboots it seems to work fine now.

Stopped working again. Can't reach gateway of deco. Checked multiple devices. Did a power cycle. Works again. Nothing in the log around 22:50 only at 23:02 when I pulled the plug. Going to check that page about firmware recover tomorrow. I thought app based settings for a router were nice but it ain't.
