What should I do if I can't get online after resetting the router? After restoring the factory password forgotten, redial the full sequence of redialing to access the internet

recently, I forgot the backend login password for my TP-Link router at home. I tried several times but couldn't get in, so in a panic, I used a toothpick to long-press the reset port on the back for 8 seconds. The lights flashed once, then turned off and then turned back on. The router was still working, but as soon as I connected my phone to WiFi, I found that web pages wouldn't open and I couldn't access the internet.

first thought at the time was, "Could it be that the router has been broken?" Later, I realized: after restoring the factory, all the broadband account passwords, WiFi names, and settings I had changed myself were all cleared from the router. It reverted to the default state I had just bought, and in default mode, it wouldn't automatically dial up the internet for you. So this article is the complete order I went from "unable to get online after reset" to "being able to get online again." Just follow it once.

clarify first: Why can't I connect to the internet after resetting

you need to figure out your home broadband connection first, otherwise you won't get online even if you set up random settings. There are basically two main ways to connect home broadband in China

the first option: the optical modem can directly access the internet (the telecom and Unicom technician will come to install it, the modem will dial the number yourself, and the router's WAN port will be plugged into the optical modem's LAN port, just set to "Automatic IP Acquisition"). With this type of device, after resetting the router, as long as the internet connection method remains the default dynamic IP, plugging in usually works immediately.

the second type: the optical modem is in bridge mode and relies on the router for dial-up (my family uses this method; the modem only handles the photoelectric conversion, while PPPoE dialing is done on the router). This is the worst part: after resetting the router, the broadband account and password are gone. If you don't re-enter it, it will never be able to dial in. It shows that WiFi can connect, but web pages just won't open.

determine which type you belong to. The simplest way is: reset: Before installing the router, did the technician ask you to enter a broadband account number (usually an area code + letters, like starting with njtelecom) and password? If you fill it out, it's the second option: you have to honestly redial the next number; If you haven't filled it in before, just plug it in and use it. This is the first type. Just skip to step four and switch to WiFi.

Step one: Go first, go to 192.168.1.1, then talk about it

After

reset, the router enters its default state. The default management address is usually 192.168.1.1 (Xiaomi uses 192.168.31.1, while some Mercury Tengda models factory 192.168.0.1; check the sticker on the bottom of the router). Connect your phone to the router by default to the passwordless WiFi (usually the brand name + a suffix), or simply connect the computer to the router's LAN port with a network cable.

the browser's address bar, type 192.168.1.1. There's a pitfall I've encountered: when your phone is connected to the router's WiFi, but before dialing the number, the phone keeps saying, 'WiFi is connected, but cannot access the internet.' Some phones won't let you open 192.168.1.1 at this point, and will either jump to the ISP page or spin in circles. The solution is to turn off mobile data on your phone, clear your browser cache, or simply connect a computer network cable to a LAN port for the most stable solution.

After entering the

, you'll be asked to set a management password (reset must be set on the first entry), and set a memory of 6 to 10 digits. If you can't even open the login portal, that's another matter. You can check the article on 192.168.1.1 for troubleshooting; here, it's assumed you can get in.

Step 2: Find Internet Mode Settings and select the correct type

After

in the backend, find menus like "Internet Settings" or "WAN Port Settings" and "Network Parameters" (TP-Link is under "Routing Settings - Internet Settings," while the older version on Mercury is called "Network Settings - WAN Port Settings"). The page will ask you to select your internet access method, usually four options:

previously determined which type you are: the first type is that the optical modem dials by itself, so choose dynamic IPs; For the second router dial-up type, choose PPPoE. My home is the second type, so let's use PPPoE as an example below. If you really can't tell, choose 'Auto Check.' Nowadays, new routers will detect it automatically. If it detects and wants to dial up, it will pop up a box asking you to fill in your account, which means you've made your choice.

Step 3: Enter your broadband account and password, then dial up

select PPPoE, the two input boxes below are broadband account and password. Many people can't find the account string after resetting, but three places can be found: first, the acceptance form from the carrier when I installed broadband back then, which says it says; Second, call broadband customer service to provide your home address and the installer's name to get them back (Telecom 10000, Unicom 10010, China Mobile 10086); Third, some stickers on the bottom of the optical modem will be written (but in bridge mode, the optical modem may not have them).

fill in the "Connect" or "Save" button. This step requires attention to one thing: the status of the WAN port. The settings page usually displays "Connection Status: Connected" or assigns an IP address to the WAN port (usually a public IP starting with 100 or a private IP starting with 10). As long as the status shows 'connected' and you have obtained the IP, it means the dialing was successful. At this point, try opening a webpage on your phone—chances are, you can get in.

shows "Connecting" but keeps redirecting, or "PPPoE authentication failed," it's 90% likely due to the wrong account or password. In passwords, uppercase and lowercase letters, the letter 'o', and the number 0 are often confused. That time, I mistook the lowercase letter 'l' for the number 1 in the password and corrected it three times before it finally connected. There's another pitfall: some broadband accounts in certain regions require extensions, such as "njtelecom123456" instead of just "123456"; the line on the acceptance form is the standard.

Step

4: Conveniently change the WiFi and management password back

the internet is available, don't be too quick to stop. After factory reset, WiFi is the default name + default password, so your neighbors can connect freely; The management password is also the first password you just set. Now, while everyone is in the background, let's do it all at once:

find "Wireless Settings" or "WiFi Settings," change the SSID (WiFi name) back to your original size, choose WPA2-PSK as the encryption method, and set the password to be a mix of 10 letters and numbers. I strongly recommend not setting the WiFi password and the router's backend management password the same — the background password prevents others from tampering with your router, while the WiFi password prevents internet access. The two are different doors. I used to set one for convenience, but later someone changed the WiFi name in the background and I realized it. For details on what to do first and what to do later, you can refer to the article the security settings I did after logging in I followed that one later.

another note: If you reset not because you forgot the password, but because the 192.168.1.1 login page at home keeps popping up incorrectly and you can't tell whether the router entered is the optical modem or the router, then after resetting this time, just change the router's LAN port IP (for example, to 192.168.2.1), and the two sides won't have conflicts. The whole issue is the optical modem and router share the same IP conflict That article explained it thoroughly. After resetting, it's the perfect time to modify this.

still can't get online? Three types of follow-up checks

you still can't get up after walking on it, check in these three directions and you'll basically be able to cover it:

First, the account password is correct, but you just can't dial it. Think about whether you owe bills, or maybe before the last reset, this account was already tied to another router and the carrier didn't release it. Call customer service and ask the backend to help you "reactivate your account" or "unbind your MAC address." In many regions, only one router can dial per broadband, so you need to notify you when switching devices.

Second, you might think it's for router dialing, but actually the optical modem is the dialing modem. How to check: Plug the router's WAN port directly into the computer. Set up a broadband connection on the computer and dial with your account. If you can dial, it means the account is fine—the router settings are incorrect. The computer wouldn't turn on either, most likely due to issues with the optical modem, so a technician would have to come and check if the modem had been switched to router mode.

Third, the computer can access the webpage, but the phone connected to WiFi cannot open the webpage. This usually means the computer still stores the old IP cache from before the reset. In the Start menu, search for cmd, type ipconfig/flushdns to clear the DNS cache, then arp -d to clear the ARP table, and reacquire it. For phones, disconnect from WiFi and reconnect once, and it's basically fine.

one last thing: before resetting, if you just forgot the background password but you can still access the internet, don't rush to plug the reset hole. There's a way to recover the background password without touching it, which I only found out later. I specifically wrote about this in the article about how to recover the login password you forgot in the backend, saving you the whole hassle of redialing. When it comes to the essential reset step, just follow the order above—from entering 192.168.1.1 to dialing again. It takes half an hour to finish.
