Hi there,
 
	We recently upgraded to FTTP with download speeds being 250mbps. I have 2 issues, one being the download speeds and my PC not appearing online in the device manager. 
 
	 
 
	For download speeds, my PC is connected through a Telstra Booster Gen 3 via ethernet cable. I have tested download speeds on OOKLA showing speeds down to 30mbps. But when I do a speed test through the optimiser it shows the normal speeds. I have tried different ethernet cables, connecting only through WIFI and even changing WIFI channels (6 to 1; advised by NBN support). 
 
	 
 
	For device manager, my PC keeps appearing offline. Like I said before, I've tried different ethernet cables, WIFI but nothing seems to make my PC appear online. 
 
	 
 
	I don't have the best understanding on how all of this works so please bare with me but I'd appreciate any help.
 
	 
 
	Thanks
