If your 2.4 GHz space is not congested and broadband plan is upto 70Mbps then you can use cheap 1000 rs routers. I get 60-65 Mbps across two walls using TP link WR 840N. For low-end 5 GHz router, TP Link C6/A6 is a decent option. 5 GHz range in this router is not great. So, make sure you do not have more than one wall here for good speeds.
One more thing to keep in mind while reading USA based reviews is that they have wooden walls whereas in India we have brick walls. So, the performance is not the same.
Fellow forum member lightgamer has used TP Link C6/A6 and C1200, his views on both:
"You can look at the C1200 if you have a strict budget of ₹3000. It costs just ₹500 more than the C6/A6 and has much better signal retention for 5GHz. I was able to get signal despite there being a cupboard and a full bathroom between me and router + 25 feet distance. For me, the difference between the C1200 and A6 was beyond massive. Where A6 was unusable C1200 had more than 100 Mbps signal remaining.
If you have a slightly higher budget than the C1200, look at the C80. It has 3x3 MiMo so even your 2.4 GHz band will be able to reach ~100 Mbps with a recent phone/laptop. The C80 also has smart band selection option where you can name both SSIDs the same and as you go out of range it will automatically switch your device to 2.4 GHz without disconnection."
