TL-MR6400 v4 error upgrade
Hello,
I have a TL-MR6400 v4 00000001 with firmware 1.7.0 0.9.1 v0001.0 Build 181214 Rel.49556n. If I launch a check for upgrade I can find the version 1.16.0 0.9.1 v0001.0 Build 191223 Rel.66638n but when the modem try to install it I receive the error: error code 71211, it seems that you select a wrong file. Same error if I download the file from tplink site and upload it. Why this happen?
Thanks

Hi,
Thank you for the information.
When and where did you purchase the router? Did you get it from your ISP?
Please also check the version of the router. You can send me a picture of the label via message.
