Roku Express doesnt recognize Wi-FI network.
it recognizes several networks in the area, however not my own.
on my router 2.4 and 5 available, switch to only 2.4 does not solve the issue
IPv6 or IPv4 does not make any difference
Mobile hotspot on iphone is recognized.
Any other suggestions?
What channel is your 2.4 GHz network broadcasting on? If it's not one of 1, 6, or 11, try forcing it to one of those channels. You may need to try all three before you find one it can use reliably.
