I recently updated the firmware on my home router, hoping to fix some security issues. But since then, my Wi-Fi has been crawling at a snail’s pace, especially on the devices farthest from the router. I’ve tried rebooting the router a couple of times, moved it to a more central spot in the house, and even reset network settings on my laptop and phone, but no luck so far. It’s weird because the wired connection still feels fine, so I’m pretty sure it’s a Wi-Fi or router-specific issue. I’m running a mid-range router from a popular brand, nothing super fancy. Has anyone else run into slow Wi-Fi problems right after a firmware update? What did you do to get your speed back up? Would rolling back the firmware be a bad idea, or are there better tweaks I can try first?

Sounds frustrating! Firmware updates can sometimes change default settings or mess with your router’s radio channels, which might explain the slowdown on Wi-Fi but not wired. Have you checked if the update reset your Wi-Fi to a lower channel width (like 20MHz instead of 40 or 80MHz)? Also, some routers enable new security features like WPA3 by default after updates, and older devices might struggle with that.

Before rolling back, try logging into the router’s admin panel and manually tweaking the wireless settings—switch channels, adjust channel width, or even temporarily disable any new security modes to see if that helps. If nothing improves, rolling back could be a safe fallback, but keep an eye out for any newer patches from the manufacturer that might fix the issue.

Sounds frustrating! Firmware updates can sometimes change default settings or mess with channel selection, which might explain the slower Wi-Fi at the edges of your home. If you haven’t already, try logging into the router’s admin panel and manually setting the Wi-Fi channel to a less congested one—sometimes auto-select doesn’t pick the best option after an update.

Also, check if the update enabled any new features like QoS or band steering that could be prioritizing wired connections or certain devices over others. Tweaking or temporarily disabling those might help. Rolling back firmware is usually safe if you can find the previous version on the manufacturer’s site, but I’d try these adjustments first since rolling back can sometimes expose you to the security issues you wanted to fix.

One more thing: some folks have had luck doing a full factory reset after an update to clear out any conflicting settings, then reconfiguring from scratch. It’s a bit of a hassle but
