Wifi connection, wrong password

By XzrT ·
Hello,

I have a smartphone Huawei Y6 2018 and since around one week it does not connect anymore to the Wifi of my box, it says wrong password. That is not true other devices can connect with the same password. I tried to rested, my box, the smartphone, forget the network and as a last resort I reinitialized the smartphone to the original configuration, it did not wok and I am in trouble now. I would like to know what could cause this problem and if the smartphone is definitely concerning WiFi. A strange thing is it can still connect to free WiFi. I precise I have checked if some MAC address were blocked, but no there is no block coming from my box.

Thank you for your answers.

Just checking one thing.

Did you tell the phone to FORGET this connection?

Is there anything odd about the password?

Also I have a new WiFi 6 router and a few phones hate it so I have a second access point that uses old WiFi WPA2.

Yes that is one of the thing I did first. For the router it is in WiFi 4 with a WPA/WPA2 PSK. Nothing odd with the password, I even change it just in case but it still does not work.

"WPA/WPA2-PSK (TKIP/AES): This enables both WPA and WPA2 with both TKIP and AES. This provides maximum compatibility with any ancient devices you might have, but also ensures an attacker can breach your network by cracking the lowest-common-denominator encryption scheme. This TKIP+AES option may also be called WPA2-PSK “mixed” mode. Don't be fooled, this is not the standard you want to be using." - https://bellinghamit.com/blog/using-right-wifi-security-wpa-wpa2-aes-wpa2-tkip-mean

Because phones update it's possible the move to more security could break older WiFi protocols.

Try "WPA2-PSK (AES) (recommended): Here's the one we want. It's the most secure of the bunch at the moment. It uses WPA2, the latest Wi-Fi encryption standard, and the latest AES encryption protocol. You should be using this option."

Also, be sure the router firmware is current. Because your phone works with other routers it's either this or the router is on the wrong channel.

Yeah for the WPA I know, I changed it just for testing if it was changing something but no.

For the router I do not know I tested with two computers and a tablet and there is no problem it connect immediately.

Let's recap.

The router is:
1. Up to date.
2. It's been factory reset and the fewest changes made for testing.

Remember that because it works with other computers does not mean it's a good router. We still have more testing then we swap out routers.

3. The channel is for your country in both router and devices.
4. You did set it to WPA2 as noted.
5. The password is very plain for testing.

I will be a hard person to convince the problem is with the phone since the phone works on other routers.

Well I thank you for your help it seems it was the router who needs to be factory reset I did not do that because I had never modify parameters before it does not work, I did not thought it could crash like that.

Thanks for the report.

One of the many computer and network mysteries. Sorry that I can't tell why resets are a fix but it beats having to replace the router or spend hours seeing if it's this or that setting.

Again, thanks for the update.

Re: password

You write it works with "free WiFi". Paying doesn't seem to make a difference, so a better test might be if it works at another password protected WiFi. Try a friend or family member with WiFi in the same frequency band (2.4 or 5 Ghz) as your router uses).
