All of the sudden this morning my Roku express lagged and then got a low signal error. Additionally the Roku does not "see" our 5G network (which i understand is faster but without a good range). Where before it would see this
i reset my Roku, reset my router and searched online. I see several posts to getting the free hdmi extender and tried to fill out the form but I'm consistently told my serial number is wrong.
initially I thought I was reading wrong but then found a way to access through my Roku and typed that number in, same result. I tried replacing Th e zeros with O's and visa versa but same result.
i did see posts which referred to a "secret internet" and internet channels (ie not like channels one watches but rather for connecting not overlapping). I couldn't figure out where to find / access this.
I welcome any help or suggestions--I'm about ready to try a different product.
Here is a link to a photo of tech specs of my device including serial number
I can answer one part of your post: the free HDMI extender is only offered for Roku streaming sticks, not for other units that connect to the tv through an HDMI cable. That's why it rejects your serial number when you try to order.
Roku Streaming Stick +, 3810X, Ser YH0059427035, wifi - Samsung UN55ES6100
Roku Streaming Stick, 3600X, Ser 5S56D8240827, wifi - JVC EM37T
Please be aware the Roku Express is only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Have you tried changing the wireless broadcast channel on the router to see if this will allow your device to connect?
If you are still unable to resolve your issue, please send me a PM with your Roku account email address, and include the serial number of the Roku device from Settings>System>About. I'll be able to assist you further from there.
Some people have had success testing theirs connected to their phone's hotspot to prove it's not the hardware, but if even that doesn't work for you, the only other thing to try, other than the router settings mentioned in other threads, would be to bring it to a friend's house to test with a different router.
