The Umobile 5G router does getting hot but I feel not freaking hot as my TP LINK AX50 router.
I also discovered that connecting my smart TV watching Netflix is much faster, smoother and no degradation using the TP LINK AX50 wifi rather than using the Umobile 5G router wifi. I connected the Umobile router to the WAN port of the AX50 router. Now I have 2 wifi address at home ha ha. The Umobile 5G router is like a book no antenna whatsoever. The AX50 router got 4 lonnnnggg antenna. Just my 3 cents.
