Bangalore, March 14 2016: A  WiFi router which helps home users to access internet on multiple devices using just one  broadband cable connection is fairly common these days.  But how  reliable are such  wired data connections?  Unless the service provider has provided his own UPS at the cable  head, chances are the connection will trip  every time  power fails in your apartment  and the genset kicks in. 
Now, TP-Link has addressed this common problem, by incorporating a SIM slot in its   Archer MR200router.  If your cable data connection works,  it is the more economical way to work.  But when it fails,  you can  switch over to the SIM -- and this router takes 4G SIMS which means  your data speeds might be even faster than cable -- theoretically around 150 MBPS. But I am yet to achieve anything more than 30 MBPS from an Indian 4G SIM.
This is a dual band router -- 2.4 GHz and 5 GHZ -- which means, it uses two distinct wireless networks,  which makes for better, more stable connections. 
Since  good dual antenna  WiFi routers cost around Rs 5000 -- Rs 6000,  the asking price of Rs 8, 999 for the TP-Link Archer MR 200,  may not seem excessive, considering  the additional  4G SIM capability.  However,   the raw rating is that of an 'n' router (802.11 b/g/n) . We wish they had gone to  the faster  'ac'    rating,  since this has been around for over a year now.
