Patch download speed

I stopped playing about 8 months ago. I came back for Shadowlands which I purchased yesterday. My update settings are set to unlimited and my bandwidth is 48+mbps down. My fastest download speed on this patch has been 72kbps and slowest has been 30kbps. It’s been downloading for 12 hours already and at this rate it will take another 2 full days to download the remaining 11gb. I can’t even play the game which means I will have wasted at least 2 days of the free play time included in the expansion purchase. Intermittent issues; I understand but these sub 1mbps speeds are constant since start of downloading. I’ve deleted cache, rebooted modem, router & pc. Anyone else seeing this issue or have any suggestions to increase my download speed?
