I’m the same at my house its piss poor signal here I had a increase for me at home now and it seems to be more reliable and more stable on my drive to work and At work..I had it constantly changing from LTE to 5G none stop now stays stableI just tried resetting network settings and had no discernible improvement. Seems worse on 5G than LTE. But I won’t know for sure until I am in a better cell area. Signal at my house is weak. Usable but not good for testing this issue.
