Many friends want to use old phones as a "wire relay" or "sign amplifier". However, since the “bridge” function of mobile phones and the professional router repeater are very different, it needs to be detailed. In general, mobile phones cannot expand wifi by working in a standard bridge mode like a professional wireless router with a “wireless client plus wireless access point”. However, a similar objective of “extension network coverage” can be achieved in several ways。
Method i: adoptionUsb network sharing(most stable, recommended)
This method, which essentially connects a cell phone to a wifi signal and shares it through usb lines to a device that does not have a wireless card (e. G. A desktop computer), does not create a new wifi signal。
Application scenario: provide wireless network connectivity to desktop computers. Operational steps:
1. Wifi connected to the main router。
2. Connect mobile phones to computers using usb data lines。
3. Anjo: access to settings > network and internet > hotspots and network sharing to open usb network sharing。
4. Iphone: enter > personal hotspots, open allow others to join and ensure maximum compatibility has been opened. When connected to usb, computers are usually automatically identified。
Method two: from the cell phone."Move hotspotsFunction (limited)
This is the most frequently misunderstood approach. Mobile mobile hotspots are defaulted to convert cellular mobile data (4g/5g) to wifi, instead of sharing it again。
However, some of the andre mobile phones (especially the country's production cards, such as millet, valor, honor, etc.) have special features:
Function name: wlan signal bridge, wireless bridge, wifi network sharing, wifi hotspot extension, etc。
The principle: the phone connects to the main route by wifi, then turns on this special hotspot, which will create a new, independent wifi network. The device that connects to this hot spot will be "jumping" to the main router via the mobile phone。
Operational steps (for example, common brands):
1. Ensure that mobile phones are connected to wifi, the main router you want to expand。
2. Enter the > personal hotspot or connect and share。
3. Find and open options similar to wlan signal bridge, wifi network sharing。
Set the name (ssid) and password for the new hotspot。
5. Other devices search and connect to the new hotspot created by this mobile phone and are available online。
Important shortcomings:
There is a serious loss of speed: data need to be “receiving and re-transmitting” on the same wireless card on the mobile phone, which is inefficient, and the speed and delay of the network will decrease significantly。
Unstable: cellular fever as a hot spot increases and may result in loss of flow due to overheating。
Expensive electrodes fast: need to be charged at all times。
Limited coverage: cell phones have much less antenna power than routers and little improved coverage。
Method iii: use of third-party app (principles and methods ii, more unstable)
Some web tool apps (e. G. “fqrouter2”, “netshare” etc.) claim to be able to achieve wifi relay. Most of them use mobile phones to create local vpns or agents, or they require all clients to install the same app, setting up complex, incompatible, highly ineffective and strongly dissuasive。
Summary
Methodology
Nature
Strengths
Disadvantages
Recommended
Usb network sharing
Wire sharing network
Very stable. Small speed loss
Only one cable, not wi-fi
(for specific scenarios)
System with wlan bridge
Wireless trunking (software level)
No extra equipment. Use old phones
Slow, delayed, heat-consuming
(temporary emergency)
Third party app
Non-standard network sharing
Theoretically, it works
It's extremely unstable. It's almost useless
(not recommended)
Conclusion: widening wifi with a mobile phone router is only suitable for temporary, lightweight emergency scenarios (e. G., providing a web line for desktops or temporarily enhancing signals in a corner)。
