Hi, I have just updated my router to 4.3.25, but the 2.4g and 5g wifi connections are now super slow and at times with no connection at all. how can I solve this? Thank you.
Finding a "good" firmware version for SFT1200 needs multiple trials. Even full config reset between upgrade/downgrades are needed as imbedded setup files differ between versions.
It is always something different that fails. Latest beta 4.7.2 beta3 is the best for me. But your mileage may vary.
V4.7.2 optimizes a lot of content, including repeater. You can perform an upgrade test.
If the WiFi becomes slow after the upgrade, you can also downgrade back to the previous version.
WiFi is always affected by many factors.
