Could you please help me with my Dlink router DWR-933? The product originally came from Saudi Arabia(Middle East) and was brought here to the Philippines(SE Asia) in 2019 with FW version (1.02 ME) and it works perfectly fine using 3G only.
Moreover, I found this thread https://www.dlink-forum.it/d/4235 in Google which I thought the speed of cellular would help maximize the LTE-A capability after the 1.11 EU FW update.
I was able to update FW to 1.11EU, 1.12EU, and 1.13EU without any error but it only resulted in "NO SIGNAL".
I downgraded it back to 1.06EU which is not ever better because now it only detects 2G network.
Can you help me understand this? Is there a way we can solve the LTE-A capability? Thank you & more power!
