TP Link WR941ND Wi-Fi Router
I recently purchased TP-Link Wi-Fi Router WRT941ND on Amazon India. Since my mobile as well as Laptops both connect to internet, I needed a device to share internet connections with them. I decided to zero in on this router because of 3 antennas, Wi-Fi 802.11n and NO Nonsense features like cloud routing. Below is the purchase link for this router if you want to purchase it in India.
 

The router was dispatched to me immediately and set up was very easy. One can set up the router either through router’s setup URL or can install it via CD. Both the methods are effective and work fine.

Performance

After setting the router up, I tried connecting to it from room diagonally opposite to room where router was placed. I was able to connect to router with signal strength of 80% which show 4 bars. Signal Strength as shown in Tray

Then I loaded Chrome tried to access websites, I was able to access Facebook, Gmail but couldn’t access Yahoo! and other smaller websites. Initially I thought of site being down or some sort of censorship. I spent some days ignoring and hoping problem would resolve. After waiting for many days I googled for cause of problem. I later came across this site named small business computing which published an article which told the root cause of problem (link). Then I found out the root cause of problem was MTU (Maximum Transmission Unit) size being too high. After reducing the MTU Size, the sites and everything started working normally. Follow the steps below to set MTU Size.

Advanced Setup screen to adjust MTU Size

Troubleshooting Tip: Setting the MTU Size

  1. access the router’s web control panel by typing following URL “http://tplinklogin.net/” [Tip: This works even if there is no internet] or “http://192.168.0.1:80/” [Tip:This IP address is specific to router and network config hence double check before use] in address bar of your browser.
  2. Login to control panel typing username and password you set while router’s initial set up.
  3. Go to Network->WAN as shown in above images.
  4. In WAN settings click on “Advanced” button at the bottom of page.
  5. In advanced settings page decrease MTU size by 10 and click save
  6. Open the sites which were not loading initially in another tab or window,
    If the sites load properly close the router control pane and enjoy!
    otherwise repeat the step 5 till the sites are accessible.

Remember: Maximum MTU Size for DSL connections is 1492, most websites on internet use 576 as their MTU Size. For more info on this problem read from this link. The Problem of MTU Size affects all routers, hence know how to change MTU for your router by visiting manufacturer’s website.

Conclusion

Performance wise this router delivers a decent performance. The pricier sibling of this router WR1041ND provides more features like USB and Gigabit Ethernet at Higher Price. Due to its much lower price there are some tradeoffs one has to make while buying this router. due to absence of USB port one has to forgo some USB functionality like print servers. The LAN & WAN ports on router are not gigabit ports hence do not expect superfast Ethernet.

Despite the tradeoffs, this router is still worth buying. If you want much more bargain, then consider buying WR10141ND which sells around INR 4000. Or you could wait for 802.11ac routers which offers gigabit Wi-Fi experience.
