I'm experiencing consistently very slow (under 1MBs) download speeds via my Huawei B315s modem, but I can get 20mbs LTE speeds from my iPhone in the same time / location. Both Optus network.
Is there something I can do to achieve the same speeds on my 4G modem?
I wonder if this is related to some of the ongoing issues that have been identified with the customers who migrated from wireless products that Optus acquired.
Possibly if you migrated over from Vivid Wireless, is that the case?
