You must be surprised by knowing the fact that Wi-Fi routers have their own memory and it stores four different types of memory in its storage. Moreover, most routers come with 64-512 MB storage capacity which is more than enough for the device to smoothly perform its function.
Wi-Fi routers have these four different types of memory RAM (Random-Access-Memory), ROM (Read-Only-Memory), NVRAM (Non-Volatile Random Access Memory) and flash RAM.
We will discuss the above-mentioned types and also how your Wi-Fi router uses it in order to support an uninterrupted internet experience.
ROM (Read-Only-Memory) and Its Function in Router
ROM is defined as permanent storage memory and the router does not lose it even powered off. This permanent memory is used for performing all-time functions for a router such as the Bootstrap startup program. Every time the router initializes the operating system uses the ROM to run all relevant data in order to do so.
RAM (Random Access Memory) and Its Function in Router
The biggest difference between ROM and RAM, ROM never loses its memory but RAM lost all its stored memory once turn-off the device. This type of memory is used for storing cache entries, storing routing tables, and performing packet buffering.
There is a big amount of temporary data stored in RAM which helps the router in retrieving it at a faster speed to keep sending the data packets to multiple devices connected. But all data will be lost once it is powered off.
NVRAM(Non-Volatile Random Access Memory) and Its Function in Router
It is the most powerful and dynamic type of memory which can be stored even router is powered-off, but unlike ROM it can also be deleted from the permanent storage when user wants. It is used for performing specific special functions and running files such as startup configuration files and backup files.
Flash Memory and Its Function in Router
This is a type of memory that can be erased and reprogrammed for new instructions. This memory holds the full operating system image and capable of upgrading the operating system without removing it.
Why More RAM or Memory is Important in Router?
The faster and more Ram empowers the router to handle more threads, this means sending and receiving big amounts of data packets in multiple streaming on the router’s network because multiple devices are connected and aggressively using the internet (Video Streaming or Gaming).
Can We Access Our Data History On Wi-Fi Router?
You can definitely access your internet history on logs maintained by Wi-Fi router. Unless you are using the VPN and performing suspicious activities on the internet then the Wi-Fi owner cannot check your internet history. Otherwise, your personal data can easily be accessed if its logging feature is enabled.
It is recommended always be using a VPN on public Wi-Fi network, otherwise, you can be a victim of cyber snooping and an attacker can break your privacy. The most popular VPN names are NordVPN, Express VPN, Surfshark and ExpressVPN.
What Type of Information Your Wi-Fi Router Stores?
Your routers store the crucial information to ensure the device’s security, prevent unauthorized access and improve its operating efficiency. These are a few examples of information that Wi-Fi router stores such as admin passwords, routing tables, configuration files and PPPoE credentials.
It also stores the URLs address of all the sites you visited and its permalinks.
How Long My Wi-Fi Router Can Maintain Internet History / Personal Records?
It all depends upon the settings you have set on it, otherwise it will maintain the logs as per by default settings set by the manufacturer. It can keep the record as long as several months without losing single entry.
Why Router Requires More RAM?
Wi-Fi router needs more RAM to prevent network congestion and improve the rate of sending data packets flow to several devices connected with router.
However, if you or your family members using uTorrent while connected with the Wi-Fi router, then your router requires more RAM to improve the data flow because uTorrent opens several other applications in the background which also requires receiving data packets and this pressure leads to network congestion.
uTorrents puts the pressure on the router and the device cannot handle it as long as having a sufficient amount of RAM. It should be offering 512MB Ram if you are a frequent user of uTorrent and ad blocker.
Can We Upgrade RAM On A Wi-Fi Router?
Though, the manufacturers of routers never design it as upgradable like computers are. But, there is one technique that enables the user to upgrade Ram on the router to prevent network congestion.
All you need to find a compatible memory chip and learn the soldering skills from the below YouTube video.
The person in the below YouTube video applies his soldering skills in order to upgrade the RAM and you can learn from it.
What is the Time Interval of Router’s History Reset?
There is no specific time period of history reset on the router. It depends upon the manufacturer which factor they set by default for history reset. There are usually three factors that cause history reset and delete the old history permanently.
First, if user performs router’s reset then history will be deleted. Second, if router is turned-off will also delete the existing history and it will be reset for next turn.
The third and final factory which causes router’s history reset, if number of entries in the activity log exceeds the limit defined by the manufacturer on the time of manufacturing.
How To Avoid Registering Your Activity on Router’s Memory and History Record?
You can definitely avoid registering your internal browsing activities on router’s memory and maintaining the data privacy. You need to be downloading and using the VPN for browsing the websites. VPN are designed to hide your all activities and the address of sites you visited.
Routers perform this function by encrypting your internet data and it is not eve exposed to a search engine.
The encryption process is already taken place by the VPN before the data gets recognized by device.
VPN is the best tool that prevents your Wi-Fi router from registering your internet history.
Final Words: Do Routers Have Memory To Store Internet Data?
Wi-Fi routers have four different types of memory used for performing its functions in the most efficient manner. Memory helps in maintaining the internet data flow, reduce network congestion and handle multiple threads to entertain several devices connected with router.
The big disadvantage of buying a router with low memory as it may start getting problems after multiple devices gets connected to it.
