Apologies if this has been covered?

Super excitied that I now have fibre UFB after over a 2yr delay for various things. I've chosen a 100/20 plan and don't get those speeds - fairly happy with this as I understand real-world speeds don't match advertised offerings.

So, what I'm asking is if it is possible (advisable even), to make tweaks to the router settings to optimise a connection and hence push the real-world speeds a little? If so - then what please?

As an aside, I bought a Zonedirector and Ruckus 7363, cheapas off Tme and switched off my Slingshot wireless. Now wireless coverage is much much better around the house.

As another aside, I had a call from the UK at 5am this morning and it cut out after 29mins 32 secs. This has happened three times with calls from the UK since I got UFB. Previously it cut out at 60mins (with my previous router). So, today i sent a fault email to Sshot - I got a reply within 15mins saying they had remote into my router and made a change to fix the issue. Impressed :-)

Thanks in advance for any help with the tweaks.
