I have tried many solutions on online forums for this, but none helped. Under the same WiFi network, my mobile phone and other laptops running windows or Ubuntu get a speed of around 4mbps(downloading) while my laptop (HP Pavilion P001-tx) gets around 200kbps.

The same file was used for downloading so no issue of server or so.

Few Details,

This came up when I ran the above command: 

eno1 Link encap:Ethernet HWaddr 6c:c2:17:6f:05:f6 
UP BROADCAST MULTICAST MTU:1500 Metric:1 --

lo Link encap:Local Loopback 
inet addr:127.0.0.1 Mask:255.0.0.0 
inet6 addr: ::1/128 Scope:Host 
UP LOOPBACK RUNNING MTU:65536 Metric:1 --

wlo1 Link encap:Ethernet HWaddr 14:2d:27:dc:93:57

inet6 addr: fe80::162d:27ff:fedc:9357/64 Scope:Link 
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 –

Running tracepath, I get,

1?: [LOCALHOST]                                         pmtu 1500

From looking at the formatted results, your wifi (wlo1) MTU is too large, leading every packet to be fragmented. If you get your IP address via DHCP, the DHCP server should set your MTU (fix it there), or to do it manually,

You can find your correct MTU value via

tracepath -n 8.8.8.8

It's a function of WiFi, PPPoE, and whatever else is between you and the Internet.

If it turns out to be, say, 1432, change it locally by: 

sudo ifconfig wlo1 down
sudo ifconfig wlo1 mtu 1432
sudo ifconfig wlo1 up
