Access wifi on desktop

V

Want internet access on my desktop using my airtel 4G without having to physically connect my smartphone using tethering.

As my desktop is old I don't want to spend much. Will this be enough: Terabyte Usb 2.0 Wireless Wifi 802.11N USB Adapter - Terabyte : Flipkart.com!

Can I expect decent speed using above adapter? I get 10 to 20 mbps with tethering by using cable.

Tethering is only good if you have no other choice. A dedicated wifi adapter will definitely be much more helpful.

I am using tethering only temporarily to see if i can get 4g speed on my desktop.
I just wanted to know if the wifi adapter I mentioned in my first post will be enough to get decent speeds. I am bit sceptical since it is priced less compared to other adapters atleast on flipkart.

If it supports 802.11n you will get the speed you want since 802.11n has a band of 5 GHz and max bandwidth of 600 megabits per second.

Of course, your wifi router or access point must also be capable of creating a 802.11n network though most adapters are backwards compatible with 802.11a, 802.11b and 802.11g as well.

I don't think that would be the case.. Usb tethering should be faster than wifi hotspot or atleast comparable to. Gentle Note : OP is not using a dedicated router, but a hotspot..

OP: Short answer yes, that wifi adapter should get decent speeds , it maybe better to get one with an antenna , like this Terabyte Wireless WiFi Connnector 802.11n/g/b Dongle WiFi Network LAN Card long range USB Adapter - Terabyte : Flipkart.com .
I had a similar looking one. They work well.Although I destroyed mine by opening it, so can't really comment on quality.

Get the one by Tp-Link and you will surely get decent 4g speeds.

That may be the case but you have to keep your phone around all the time so that's kind of not very convenient IMO.

99% of wifi n devices in India are single band 2.4GHz,cheapest 5Ghz wifi adapter I have seen starts at ~Rs.900.In fact nowadays it will be hard to even find "dual band n" devices & instead you will get 5GHz ac wifi devices but then even many mobiles too don't have 5GHz/ac wifi support.

Oh well.
The wifi adapter I currently use is one from 2014 and it supports a, b and g so I thought new ones will also be backwards compatible.

They are but as I said,most ac-n devices also support 2.4GHz which is also the band used by ac-g so no issues.Even ac wifi devices also have both bands(2.4GHz & 5GHz) so they too are backward compatible.Only issue is that if you connect a wifi-g device to a wifi-n network then all devices will drop down to 54mbps of wifi-g standard even if they are not wifi-g devices but are wifi-n devices.

@whitestar_999 that's good info. I mistakenly used to think that ac/n wifi means 5Ghz
Edit: ok so I was very confusion. Reason is I assumed ac wifi is same as n wifi. They are different.
AC means 5GHz, its latest . N wifi are generally 2.4Ghz, but can also support 5Ghz , depending on device.

AC wifi does mean 5GHz but it also supports 2.4GHz. Normal N devices are 2.4GHz but some N wifi devices supports both 2.4GHz & 5GHz(they are usually called dual band N devices but I think nowadays they are completely replaced by AC devices).

P.S.edited my previous post for better clarity.
