Hey guys, could do with some advice/help please...
I've got a Vodacom wifi router that is giving me the following speeds:

Ping: 29ms; Download: 3.26Mbps; Upload: 0.67Mbps

If I use my S7 Edge Duo as a hotspot it is noticeably much faster
Any ideas please?

Do you have a 3G or LTE router?
If it is LTE make sure it is connected to LTE and not 3G.
The S7 EDGE is probably connected to LTE.
