It does matter - for PPPoE the maximum MTU is 1492, for PPPoA it is 1500.
I wasn't the first to mention PPPoE
Whether that is true or not I don't know but it seems a reasonable assumption - so why risk getting an incorrect report when by picking PPPoA you know it's right?

Hi,
Yes, that information is what I wanted to see.
You settings show RWIN is too small (17520) and your PC probably has its MTU (1500 is default) mismatched with the router (1400). The expanded information plots show periods with longer "round-trip" times so I'm going to recommend a larger RWIN than PN's standard formula would suggest.
To change these settings please download DrTCP from the DSLreports website. I suggest you choose the dot-exe file, it is only 52.5kB
Double-click the downloaded file to run it (the application doesn't install on your computer), and
1. enter 108800 in the top box (RWIN),
2. make sure the Network adapter box at the bottom shows your Network card (use the drop-down menu to select if necessary - note this is not "sticky", will need to be selected again if you run DrTCP another time),
3. enter 1400 in the right-hand MTU box.
4. Click Save, then Exit.
Now you must restart your PC to ensure the changed settings take effect.
After your PC restarts hopefully you'll find download speeds improve. I'd appreciate feedback on the effect and the results from another Tweak test so I can check all looks OK.
I'm suggesting adopting MTU=1400 on your PC, rather than changing the router to 1500 because some users find websites with a lot of graphic content fail to load with the higher value.
Fingers crossed

I have my router and PC both set to 1500 and haven't found a single website that fails. The important thing is to make sure MTU path discovery is working which should automatically drop the MTU used as required.
