The United States government is thinking about banning TP-Link, a Chinese company that makes internet routers, because of concerns about national security. TP-Link’s devices are popular in the U.S., especially in homes and small businesses, holding about 65% of the market.

The investigation started after Microsoft reported that a Chinese hacking group used TP-Link routers to carry out cyberattacks. Critics say TP-Link has been slow to fix security problems in its products, which could leave users open to cyber threats. These routers are even used by some U.S. government agencies, like the Defense Department, raising fears about spying or cyber sabotage.

The Justice Department is also looking into claims that TP-Link sells routers at prices below production costs, which could hurt fair competition in the market.

TP-Link says it follows industry security standards and U.S. laws. The company is working to address national security concerns and is trying to distance itself from its Chinese roots amid growing tensions between the U.S. and China.

This possible ban is part of a larger U.S. effort to reduce cybersecurity risks linked to Chinese tech companies. In the past, the U.S. has placed restrictions on companies like Huawei and ZTE for similar reasons.

If the ban happens, it could greatly affect the U.S. router market, considering TP-Link’s large presence and the fact that many people and businesses rely on its affordable networking products.
