Extremely slow wifi speed On Acer Aspire 3

I am getting extremely slow wifi speed on arch(0.5 - 1 Mb), in contrast to windows where I can easily get 90-100Mb.
I have tried various solutions available online, ranging from disabling power saving to installing iwl, changing dns servers, installing drivers etc. But I am still not able to see an improvement in the speed. The network is not congested as only my mobile phone and laptop is connected to it, and there is no physical obstacle either as the router is just behind my table. I had looked at the wiki for solutions but nothing worked.
The laptop is Acer Aspire 3
