Any help would be appreciated. There are many Gnd pins in WiFi chip and they are all connected so i have no option of disconnecting all the ground pins to make a low side switch. R3 is ‘or safety’ to ensure Q2 turns off.
Instead of switching 3. A normal transistor would do and i experimented too. A normal transistor in saturation may even be enough to switch a small WiFi module.
Yes i am connecting datsheet gate to the ground so that i get For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn.

Why is my WiFi chip not powering up? Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. Resistor values are liable to be about right – play as required. So a Darlington may not do what you want but a single bipolar may. If irf5940n pick through a bin of these you MAY find some that work somewhat better than others and some that MAY work well enough if9540n you – but maybe not, and this cannot be guaranteed.
However, the graphs are for typical values.

I may need around mA for my WiFi. Do you have easy access to a range of parts? Post as a guest Name. The IRFN – data sheet here needs about Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research? If you draw a Darlington cct you will see it is different.

R2 not required if input is always datashfet high or low and never floats. Q2 can be a single adequately rated PNP or several smaller ones in parallel. Mosfets are incredibly sensitive to static and I have destroyed many like this.
