Why the the stronger signal AP got lower speed?

[wfqk]

Hi

An AP's signal is week, so i added one extender. I got two signals using inSSIDer. Please see attached picture. The upper picture shows the extender's signal strength -35 dBm and its Max rate 144 Mpbs. The low picture shows the AP's signal strength -49dBm and its MAX rate 216. Why the the stronger signal got lower speed? Thank you

Yup, that'll be it. 

Rule of thumb:  Every so-called "extender" cuts the speed by half.  The more the "extender" ... the fun ends.

Thanks for your reply. so is it better or not we add extender? adding extender will get stronger signal, but lower bandwidth

Adding extender will help to extend a coverage, but throughput  will decrease.

With extender, clients + extender compete for AP bandwidth. Without extender, only wireless clients compete for AP bandwidth.

In addition to Rasika's response: If someone wants more wireless coverage, do the the right thing and deploy an AP.

I just added an extender, and i can see my PC is only user which use the extender. How can we say there is some one to compete the bandwidth?
