Thank you for joining the Intel communities.
We really appreciate you have reply with this information.
In this case, I’m not sure if this is going to harm your unit after a while since this a configuration from Windows registry.
Please be aware that the onboard Realtek RTL8723BS wireless adapter is an SDIO adapter; SDIO is inherently slower than PCIe-based wireless adapters. Wi-Fi speeds can be very slow, depending on many factors:
If there are other Wi-Fi routers nearby. Router channel is set to Auto (and so is everyone else’s).
How close the unit is to the router (router is in another room; signal passes through walls/floors).
Interference from other devices (mobile phones, cordless phones, microwaves, Bluetooth devices, or baby monitors.
This is the workarounds we recommend:
Try to eliminate interference with nearby wireless devices (like microwave, cordless phones).
Experiment with setting the router channel to a specific one, not Auto. Note: 2.4GHz can use channels 1, 6, and 11.
Try hooking a second router or a router extender to your main router to spread the signal throughout the house.
Disable the onboard wireless in BIOS and use a USB-based Ethernet adapter. Wired Ethernet is always going to be faster than Wi-Fi
Thx amir_ro, I've had issues with buffering and bandwidth on my device too. Might give this a try, wouldn't surprise me. Intel doesn't seem to do much actual real world testing.
Also the support staff saying "I'm not sure if this is going to harm ..." means what? why even say something, if you don't know and then make like it will harm. Putting blame on interference, and no other device in the home has issues ... you would say it's a ICS issue.
the Realtek card inside the Intel stick is quite crappy, but it can be fast if all conditions all good.
My Intel compute stick is only 1 meter from the AP, and it can do 40-50Mbit, but sometimes speeds slow down to 2-3Mbit for no clear reason.
I have 3 devices that exhibit this slow wifi sympom at the same time: an intel compute stick, a toshiba windows tablet and a cheap chinese MK802. The first two are based on exactly the same wifi card (the mk802 is also a realtek, but I don't know which model). If these devices have their wifi problems, they are also capable of disturbing wireless keyboard signals during a download/upload.
Other devices work fine at full speed (several androids, windows PC's, chromecast, even my €200 Chromebook is rock solid at that time on the 2.4Ghz channel).
I tried changing some setting on my AP (switching 20/40Mhz or b/g/n setting), but without any results. Switching the cannel (e.g. from 3 to 4) solved the problem temporarily (for all 3 devices at once !!!). For some reason these realteks are very sensitive to some kind of interference.
