Laptop speed is inexplicabily slow

iRenato

Yesterday I modified the name of 5Ghz Wi-Fi signal as my windows laptop linked always to the 2.4 GHz 
After that I use the 5 GHz Wi-Fi signal and now the speed test is become 2-4 Mbps instead usual 200-250 Mbps 
I tried everything without find a solution 
Pleeeease some help for me
the same 5GHz Wi-Fi used by iPhone it works very fast

ciao

@iRenato, there are many reasons why this could be happening.  Let me start you on a few basics.  5Ghz band does travel as far as the 2.4, and degrades quicker then the 2.4 band. Therefore, the farther away you are, the weaker the signal will be compared to 2.4.  This could be one reason why you're seeing what you are seeing.  Also, the radio in your iPhone might be more sensitive than the one in your Laptop, which is why the iPhone might be doing better than the laptop.  

You can do a little experiment by moving the laptop to different areas, closer would be fine, and see if the situation gets better.  That would be your smoking gun if it does.

A few things to check in the meantime...

• Do you have the latest network driver for the laptop installed
• Do you have the latest OS and patches.
• Check to see if your router has the latest version of firmware.

Ciao Mark ..... it’s a pity this trick doesn’t my smoking gun ..... I start to check your list 
but first I remove the rename of 5 GHz Wi-Fi signal

OS and drivers are updated!
before to verify the router firmware I retested the speed and 491 Mbps reappeared!!

After one frustrating weekend ..... the sun is rising again ☀️ 
thank you

Marc your post says "5Ghz band does travel as far as the 2.4," is that correct??

Marc

Yup. The 5ghz band is faster by design and less congested but does not travel as far as the older 2.4.

from this site but if you google you will find more examples...

1. WiFi network coverage— When it comes to WiFi coverage, 2.4 GHz outshines 5 GHz. In the 2.4 GHz band, the lower frequencies that are transmitted here can more easily penetrate solid objects, meaning the signal can be better carried out throughout your home.
