Hello @raszei4c ,

Thanks for contacting our community.

If you are experiencing upload speed issues at higher channel widths, it may be related to wireless environment interference, device compatibility, or firmware limitations.

Since download speeds are as expected, the issue may be specific to the way certain devices (like your Galaxy S25) handle uplink transmissions at wider channel widths. 

Besides Galaxy S25, have you tested other clients? 

For the MLO connection, please keep in mind that current MLO implementations may prioritize a single band based on signal quality and network conditions, and may not always actively use both bands simultaneously for all traffic types.

When you connect to the MLO Network, would you like to use mainly 5Ghz?
