Issues to connect to wifi: wrong password message but it's correct!
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
I have installed a wifi range extender RE450 in a small guesthouse between 2 rooms.
Many people come with different devices all year long.
Since a couple weeks, I noticed some issues while trying to connect to wifi (mostly on the 5Ghz band).
Issues:
- error message: it says password incorrect but it's correct
- have to retry many times before it connects
- sometimes it won't connect to the 5Ghz, only the 2.4
- 2.4 will be very slow
Anyway, something's definitely wrong. I'm wondering what's wrong, I have not changed anything, and it was working fine.
Please help, thanks.

@MarcelN @TommyB TP link did reply
- set deco's in AP mode
- Switch off fast roaming
- no special chars in password ? (THIS WAS THE SOLUTION)
I haven't tried it out because the deco's are not in my own home. Try it later this day
-13-7 17:00 CET : leaving out the special char ! in the password did solve the issue. To me it is an issue of the DECO which TP-link denies.
But none of the Iphones, Ipad's , Sonos, Huawei, Philips TV could connect with the ! in the password. And they al could when the ! was removed from the password.
TP Link first tell's me to remove special chars from the password, and then say it's unsafe NOT to use special chars
