A situation where it is necessary to gain access to the insides Wi-Fi routerProblems can arise completely unexpectedly. Most often, users encounter this problem when they need to find a hidden reset button, replace dried-out capacitors, or simply replace an antenna module to boost the signal. MTS devices are often designed for difficult user access, requiring care and an understanding of how to disassemble plastic.
Before you begin disassembling, it is important to understand that any damage to the case will automatically void the warranty. If your MTS router If the device is still under warranty, it's best to contact a service center to avoid losing your right to a free repair or replacement. However, if the warranty has expired and the device's functionality is needed for experiments or repairs, proceed with caution.
In this article, we'll take a detailed look at the process of opening popular router models, provide the necessary tools, and warn you of critical risks. Proper disassembly will allow you to extend the life of your equipment or modify it to suit your needs without making fatal mistakes.
⚠️ AttentionOpening the MTS router case will void the warranty. If the device is working properly but you simply want to reset the settings, use the software method via the web interface or the Reset button on the back panel (press and hold for 10-15 seconds).
Necessary tools and work area preparation
Effective disassembly of electronics requires not so much strength as the right tools. plastic latches For MTS routers, you'll need a basic set of tools that any DIYer can find. Lack of specialized tools can result in damage to the housing, which will then need to be repaired.
First, you'll need a thin plastic card or a special case opening tool. Using metal objects like knives or screwdrivers initially risks damaging internal cables or scratching visible parts of the case. Metal can also accidentally short-circuit contacts on the board if it's under voltage.
To remove screws, which are often hidden under stickers or feet, you'll need a set of Phillips-head screwdrivers. Depending on the router model, screws may vary in size, so it's best to have several on hand. Tweezers for removing small parts and a hair dryer for softening the adhesive if the router is glued are also helpful.
☑️ Tools for disassembling a router
Design features of MTS routers
Devices supplied by MTS are typically manufactured by major OEM partners such as Huawei, ZTE, Sercomm, or D-Link. They are divided into two main design types: classic "boxes" with vertical antennas and compact mobile routers. Understanding the design type helps predict the placement. fasteners.
In most desktop models, the primary fasteners are plastic clips around the case. However, engineers often hide two or four screws under rubber feet or decorative caps. Ignoring these hidden screws when attempting to force the case open is the most common cause of plastic tab breakage.
Mobile routers such as the series MTS Connect or the Huawei E-series, often have a more complex assembly. They may use a combination of screws and glue. Furthermore, in such devices, it's critical not to damage the cables connecting the main board to the display or control buttons, as they are very thin and fragile.
Why are MTS routers difficult to disassemble?
Manufacturers deliberately make the case difficult to open to prevent unauthorized tampering with the device, including changing the IMEI or firmware. This also reduces the number of warranty claims due to "accidental" factory resets.
Step-by-step instructions for disassembling a desktop router
Removing a traditional router requires a consistent process. First, flip the device over and carefully inspect the bottom panel. Look for stickers with technical information—screws are often hidden underneath them. Gently heat the sticker with a hairdryer or simply peel it off to access the screws.
After removing all visible screws, move on to the latches. Run a plastic card or pick along the seam between the top and bottom of the case. Move around the perimeter, applying gentle pressure while simultaneously trying to pry the halves apart. A distinctive click will signal release. plastic latch.
Once all the latches around the perimeter are released, do not yank the top cover abruptly. The antenna or LED panel connection may remain inside. Gently lift the cover and inspect the insides. If the cover does not come off, check that the central screw under the logo is not still loose.
Disassembling mobile 4G/5G routers and USB modems
MTS mobile devices such as Huawei E8372 or the ZTE MF79U, have a more compact design. Their bodies often consist of three parts: the back cover (where the battery is), the middle frame, and the front panel. Disassembly begins with removing the back cover and battery, which is a mandatory step before any intervention.
Unlike fixed models, the screws here may be hidden under a layer of glue or plugs in recesses. After removing the screws, the case often needs to be carefully heated around the perimeter, as manufacturers use glue to secure it in place. This should be done slowly, using a thin spatula.
Pay special attention to the antenna leads. In mobile routers, antennas are often thin wires soldered to the board or press-on contacts. Careless handling can cause them to break off, requiring soldering to repair. Also, protect the display cables, if your model has one.
| Device type | Screw placement | Mounting type | Risk of damage |
|---|---|---|---|
| Landline (Huawei/Sercomm) | Under the sticker/legs | Latches + 2-4 screws | Medium (breaking latches) |
| Mobile (USB stick) | Inside the case under the lid | Glue + screws | High (trains, antenna) |
| Mobile (with screen) | Under the battery and frame | Lots of screws + glue | High (screen, cables) |
| Optical Terminal (ONT) | Hidden screws | Complex latches | Medium (fiber optic) |
Common problems during dismantling and their solutions
One of the most common problems is broken plastic latches. If you hear a creaking sound but the case won't open, you may be pressing in the wrong place or missing a screw. In this case, it's best to stop and carefully inspect the device from all sides, using a flashlight to illuminate the seams.
Another problem is adhesive residue that makes it difficult to remove the cover. Avoid using force to avoid cracking the plastic. Heating with a hair dryer can help soften the adhesive, making it more flexible. Special adhesive removers can also be used, but be careful with them to avoid damaging the label or the plastic itself.
If you discover that the antenna wire has come loose from the board during disassembly, don't rush to solder it with regular tin. High-frequency connections require specialized solder and skills, otherwise you could disrupt the impedance matching and lose the signal. In such cases, it's best to contact a professional repairman.
⚠️ AttentionWhen working with a plastic case, do not use acetone or harsh solvents to remove adhesive. They can melt the plastic or make it cloudy, which will permanently ruin the appearance of the device.
Assembling the device and checking its functionality
Reassembly is performed in reverse order. Ensure all cables and wires are routed within their proper channels and will not be pinched by the case. This is especially important for antenna wires, which should not come into contact with hot components on the board or sharp plastic edges to prevent short circuits.
Don't use excessive force when snapping the case closed. If all the screws are tightened and the cables are in place, the case halves should snap together with moderate force. If significant force is required, there's a loose component or a wire interfering with the closure.
After assembly, be sure to test the device's functionality. Connect the power supply and wait for it to boot up. Check that the indicators are lit, that the device has a network connection, and that Wi-Fi is available. If the device doesn't turn on, you may have forgotten to connect an internal power connector or damaged a cable.
Frequently Asked Questions (FAQ)
Is it possible to disassemble an MTS router without damaging the seal?
It's practically impossible. The seals on the screws or casing are designed to break when opened. Even careful removal of the seal with heat or solvent leaves traces that the service center will consider a warranty violation.
Where is the reset button inside the router?
The reset button is usually a round metal pad on the board, labeled "RST" or "Reset." It may not have a mechanical button, but rather contacts that need to be connected with tweezers when the power is on.
What should I do if the router stops detecting the SIM card after assembly?
Most likely, the SIM reader contact was dislodged or damaged during disassembly, or the cable leading to the communication module became loose. You need to re-disassemble the device and check the tightness of all cable connections and the cleanliness of the contacts.
Is it dangerous to touch the board with your hands when disassembling?
Yes, there is a risk of static discharge, which can damage sensitive circuits. It is recommended to use an antistatic wrist strap or touch a grounded metal object before touching the circuit board to discharge any static electricity from your body.
