hi Guys,
I recently purchased a TLWN851ND, I can find my wifi network no problem and assess to the internet, as long as there is NO other wireless device (phone, laptop, ps4) switched on in the same network.

does it seem normal? I can use all my other devises at the same time, but not TLWN851, I have also changed my wifi channel to different numbers, all seemed same result, so at this moment, I just have to switch all devise off when I use this PC.

can anyone help with this?

thank you.
