Though it shouldn't be needed, I took the face off my Roku express and slid the electronics out. Then I took my Dremel and drilled about 1/8 holes in the top and bottom (about 10 per side). Then put it back together. It runs much cooler now and doesn't lose signal.
I have a 3900. It's signal quality is constantly poor. I configured a wireless repeater and plugged it in 10 feet from the 3900 with no obstructions. The 3900's signal strength was still poor. I replaced the 3900 with a 3920. The 3920 shows excellent for the repeater signal strength and good for the AP in my living room. I'm certain the 3900 has a hardware issue.
I just purchased a Roku Express+ for my husband as a gift to use with an older TV that only has the red-yellow-white composite connection. I'd rather not use wifi, especially after reading this thread. Is there any kind of ethernet adapter I could add so it can be hardwired, instead of wifi?
@freeplay ... nothing that I have ever seen.
@tbird635 and @freeplay , for the poor wireless signal, try the fix that I posted ... change the 2.4Ghz band on your router to use wireless G ONLY. I did NOT change my password (25characters with special characters in it) am able to connect without issue now.
I apologize, I forgot to update this. I ended up with a warranty exchange. No matter what I tried , it still had a poor signal.
The new one works like I expected it to.
I'm now connected with a strong signal with the same router set in mixed mode.
Apparently mine was a hardware issue.
Looks like I have the same issue. So frustrating!
We have 4 of these in 3 different households and ALL OF THEM ARE HORRIBLE at WiFi signal strength!
I wish I'd never bought these as Christmas gifts... 😡
