Posting again to be a 'squeeky wheel' for the internet speed test feature was apparently removed from the app for certain Deco models but has been requested to be added back via community forums:

• Bring back the speed test feature - Home Network Community (tp-link.com)
• No option to test Internet speed on Deco app (XE75) - Home Network Community (tp-link.com)
• Test Internet - Home Network Community (tp-link.com)
• no speed test - Home Network Community (tp-link.com)
• speed test missing from 6E xe75pro, we need this functionality!! - Home Network Community (tp-link.com)

As a recent purchaser of the XE5300 model, I was also surprised to find that there internet speed test feature built into the app, as this has become pretty standard with router apps.

For a specific use case of this feature, I'm currently getting 10% of my advertised download speeds to my laptop and without being able to tell what the ISP is delivering to my router, I can't determine if it's an ISP issue or a Deco router issue. I would think tp-link would want this feature to prove that it's the ISP and NOT their routers causing the speed reduction. 

Not sure how often these are monitored, but maybe for clarity's sake - is there any chance that the internet speed test feature will be re-introduced for Deco models that do not currently have it? This would be greatly appreciated and supported, if so!

If not, is there a specific reason why? Is it is hardware or software limitation? Is it an issue with Speedtest by Ookla (appears that's who it is run through for models with the feature)?

Thank you - I look forward to hearing back!
