I have had problem for a couple of months since I bought this router with 1 laptop out of 6 total devices that connect at different times. When streaming videos for a few minutes the internet disconnects though I still have connection to the router.  If I disconnect and reconnect to router it works for a random amount of time sometimes 2 minutes or less sometimes up to 10 minutes. I tried to update firmware and I get error code 4503.

Which firmware you downloaded? Looks like you have US version so I guess you can check if you download the right version or not and unzip the file and upload the bin file

Yes, thank you. I discovered that the error message 4503 indicates the firmware was actually a downgrade which was not allowed. I downloaded the corrected firmware and was successful at upgrading it.
