TP-Link TL-MR6400 300Mbps 4G Mobile Single Band Wi-Fi Router, 4 Ports, High Reception Sensitivity, No Configuration Required, with Micro SIM Card Slot, App Management

I've been using the TP-Link TL-MR6400 for a few months now, and it's been a great addition to my mobile internet setup. It's small and easy to carry around, so I can take it with me wherever I go.Pros:Affordable: The TL-MR6400 is competitively priced, making it a great option for those on a budget.Easy Setup: The setup process is straightforward, even for those who aren't tech-savvy.Stable Connection: The router provides a reliable and consistent connection, even in areas with weak 4G coverage.Multiple Connections: It can handle multiple devices simultaneously, making it ideal for households or small offices.Compact Design: The compact size makes it easy to take with you on the go.Cons:Single-band Wi-Fi: While it offers a decent range, the single-band Wi-Fi can become congested in crowded areas.Limited Features: Compared to more advanced routers, the TL-MR6400 lacks some features, such as parental controls or guest network capabilities.Overall, I'm very happy with the TL-MR6400 and would recommend it to anyone looking for a reliable and affordable 4G LTE router.

Overall it's a very good router does exactly what it is meant to do. Easy sim enter and start using. Problem is it doesnt detect Jio 4g Band 5. For those who dont know Jio uses 3 bands.Band 5 slowest and best reception deep inside the houseBand 3 faster and good reception balanced outBand 40 fastest and lowest range and stabilityThis router is only detecting band 3 and 40 which is ironic because the tower is a little far off and in my phone where it is 4g+, the 4g+ carrier aggregation is always shared between band 3 and 5 whereas 40 is never detected because its too poor and requires one to be very close to the tower. Band 5 is literally the most used by phones and any Jio 4g device for network reception. So its a big bummer that this router cannot detect that.

I am using this Router from last 10 days runing flawlessly.Very easy to install just plug and Play.I am using Airtel 4g sim speed is much more than using in mobile phone.My house is very big I placed in centre and covers entire house.Some times weaker covrange inside the rooms.But Overall coverage is very good.I am using many devices like projector,alexa echo dot,mobiles, laptop,desktop,home theater,smart devices like lamps,plugs I haven't faced any issue works smoothly.I definitely recommend this 4g router where there is no broadband connectivity.

I am a firmware engineer for last 25 years. I bought this product to work from home, during my visit to India.Got excited initially, but then the device keeps disconnecting the internet, wifi stays though. Internet speed was slow (3-5Mbps) compared to my Huawei P30 phone which was giving 30-40Mbps, and my iPhone 11 giving 30Mbps, on the same SIM. So I manually changed the LTE band (great!) and got 30Mbps on this router device. I live in the city where the signal strength is 100%, hence the higher Mbps numbers.But the trouble is that it keeps disconnecting the internet for several minutes. Tried VI and Jio SIMs and both work very well with cell phone tethering. Manually tried changing DNS servers to Google, Open DNS, Cloudflaire etc, but no luck. Really getting embarrassed on conference calls and presentations, when the voice start jittering and connections dropping out.If you are a person who buys this for your work or watching a Prime movie, do not buy this. You will be sad and spending your valuable time figuring out workarounds and searching all over for solutions.I bought this device before starting from USA because the shipping time showed a week. But they delivered a few days before so my return window was only a few days. I cannot return this device, Amazon customer service says "sorry sir" (we got your money, go away), the seller doesn't help either.I have no other option but to give a 1 star review to show my frustration.BTW, this product is hardware version 5.2, it is new and there is no firmware update available. If you happen to buy 6 months ago, it was an older version of hardware where you could use DD-WRT or other Beta firmware as a workaround. The reason I am telling this is that the 5 star reviews you are reading here are for older hardware. The new 5.2 version hardware is a brick.

Using it with prepaid Vi SIM connected to computer vial LAN (not WiFi) in a very very harsh industrial environment and it is working like a charm. It auto detects all Indian SIM card. No need for any setup if use as 4G LAN modem. Need to setup WiFi if you use WiFi. But all setup are browser based and easy setup mode is available.

Easy plug and play modem. However, you will only get 7-10 mbps max on wifi. It is incorrect to state that this is 5Ghz as mentioned in the title. It’s only 2.4Ghz and this low speeds over wifi

New jio sim is not working in my mr6400, please someday give me solution, i tried also in customer care, they don't have a solution.

My jio dongle had gone faulty and was looking for some sturdy router which can be used throughout day without any glitches. Came across this model and I have to say that it is working much better with JIO sim than its original dongle. Wifi range is ok and installation is pretty easy. Overall, if you are looking for router with 3g/4g sim slot for home, go for it.IMP NOTE:- Many people have wrote that it's not supporting JIO. If you are going to use JIO sim, please buy TP-Link TL-MR6400 model ONLY. Most of the people are buying TP-link MR200 model which support all 4g sims except JIO and posting that JIO doesn't work. Be mindful while selecting TP-Link Model.
