I have a DELL Inspiron 15 5577 laptop with an Intel 3165AC + BT4.2 [802.11ac + Bluetooth 4.2, Dual Band 2. 4&5 GHz, 1x1] WiFi modem.
Its WiFi signal is very weak; it's not even catching access points which are far away. I have tried the following:
1. I have updated all the software. I have uninstalled and then reinstalled the software. This step didn't improved the condition.
2. I have opened my laptop, removed the chip set and inserted the chip set of another healthy laptop but the condition did not elevated.
3. I have tried to put my Wireless Adapter Settings to Maximum Performance I am now very confused as what could be the issue. I am looking for a solution.
I have this problem on every WiFi I have. I have tried my phone's WiFi, my college WiFi, my friends and so on. I have made my phone an access point or tried access point available in my college but it didn't worked. I would like to mention that my other devices(like my friends laptop or my phone) can connect to the access points like in my college but the problem persist with me only.
I have my phone's hotpot currently active and its like 5cm away from my laptop. My laptop is showing full connection. If i move my phone to a meter(approximately or less than) the signal weakens to 1 bar to even zero. This problem is from every access point no matter the configuration or the channel.
As an example here, I have made my phone as an access point and these are the results:
So I have clicked a picture of my connection and as you may see I can't be more than 15cm away from it.Full WiFi connection
Distance distance of laptop and access point
WiFi connectivity after is: Connectivity with distance
I am myself a CSE 2nd year student so I would love to learn the technical also. Please Help!!
