I have starlink internet.

When i connect my phone to starlink router wifi, i get a speed test within the app over 150mbps

i have deco m9plus connected via ethernet to tplink gig switch

the deco broadcasts wifi

in the deco app, the speed test is great

however, when i connect my phone to the deco wifi, and perform speed test from starlink app, it is only around the 80mbps

what could be causing the speed drop when on deco wifi?
