I also posted on ISP Review, so apologies in advance for the double dip but thought a bit more exposure might help..
For some odd reason I can't get any data download at all on Lebara 4G with my B535-333. It only works properly on 3G. On 4G, the router is showing a good signal and an upload speed but no download speed & I can't get to any internet sites. I've tried various Voda APNs in addition the the official Lebara APN but no success.
The SIM works fine in another 4G router and also on a phone, so it's the B535-333 having the problem.
The router was originally on Three UK and works as expected on my iD mobile SIM & also on an EE SIM.
Any thoughts as what the problem is / how to resolve are welcome.
