Network maintenance keeps things working right—making sure each device and connection stays secure, updated, and ready for action. So, what does it mean to maintain a network? It’s creating a structured routine that tackles updates, security checks, and performance monitoring.
Below is a quick look at the main steps in a solid IT network maintenance routine:
- Update firmware and software
- Monitor network performance
- Optimize bandwidth usage
- Review network security settings
- Inspect and replace hardware
- Backup critical data
- Check access control lists
- Conduct vulnerability assessments
- Perform troubleshooting and diagnostics
- Build an IT network maintenance plan
Follow Meter’s network maintenance guide and keep your network running like a well-oiled machine.
1. Update firmware and software
Leaving firmware and software outdated is like keeping an old, rusted lock on your front door—eventually, someone will notice and jiggle the handle. Firmware updates are essential to keep hackers out of the network. Every update brings performance boosts, security patches, and sometimes even nifty new features that make your life easier.
No one loves scheduling updates, but a consistent routine keeps the network happy and issue-free. It’s a small investment of time that can save you hours of troubleshooting later.
A major lesson in the risks of skipping updates comes from the 2017 WannaCry ransomware attack, which hit organizations worldwide. The attack targeted unpatched Windows systems, disrupting over 300,000 computers in 150 countries, including hospitals and businesses. Microsoft had released a security patch two months before, but systems left unpatched were vulnerable to this costly, global event.
Skipping these updates might feel like you’re saving time, but trust me, the “time savings” won’t feel worth it when you’re dealing with a breach or a sluggish network. Stay ahead of the game and embrace the updates—they’re your first line of defense.
2. Monitor network performance
Latency spikes, packet loss, and uptime trends are like red flags waving at you, saying, “Pay attention here!” Catching these signals early keeps you a step ahead of disruptions.
Set up alerts for performance metrics
Automate alerts for the big stuff—latency, throughput, and error rates. Nothing should slip through unnoticed, so let the system do the watching while you focus on what matters.
Review weekly performance reports
Give those weekly reports a good look to spot any recurring issues. Patterns might pop up (like that time your bandwidth dropped every Thursday at 3 P.M.). Often, a quick adjustment is the change needed to help avoid bigger problems later on.
3. Optimize bandwidth usage
Bandwidth is a limited resource, and when it’s spread thin across a busy network, every team feels it. Giving critical applications priority can help avoid the lag and buffering that frustrates everyone—especially when vital business tools slow down because someone’s streaming the latest “must-watch” video in ultra HD.
Set priorities
Set Quality of Service (QoS) rules to keep VoIP, video calls, and core apps chugging along when things get busy. QoS acts like traffic lights for data, making sure high-priority services get the green light before others.
Identify bandwidth hogs
Network tools can help spot which apps or devices are eating up bandwidth. Identify repeat offenders and limit their usage, or consider moving data-heavy services to off-peak hours. It’s a practical way to balance needs without telling people to give up their cat videos (but maybe suggest switching to 480p).
Consider upgrades or adjustments
If your team’s regularly maxing out bandwidth, it might be time to evaluate if an upgrade or additional bandwidth allocation is needed. Sometimes, the only solution is to bring more to the table—after all, even the best prioritization can only go so far with a limited supply.
Schedule monthly reviews
Traffic changes over time, especially with new tools coming into play. Monthly checks help you stay flexible, adapting the network to meet current demand rather than yesterday’s usage patterns.
Correctly optimizing bandwidth creates a balance in productivity while giving the network the room it needs to breathe. A well-tuned network should be as quiet as it is fast, with fewer complaints and dropped calls.
4. Review network security settings
Security settings are often treated like fine china—carefully set up once and then ignored until there’s a problem. But leaving these settings unchecked can invite more trouble than you’d expect. Giving firewall rules and access controls a regular once-over can prevent unpleasant surprises, like unauthorized access or weird network behavior.
Check firewall rules and security settings at least once a quarter, but consider monthly updates if your network handles sensitive data. Think of it like a seasonal tune-up for your network’s defenses. As your network grows, rules need a refresh to stay effective. Outdated settings can slow things down or leave gaps that might as well be open doors.
Update access permissions whenever roles change. People move teams, switch roles, or leave, and nothing screams “security risk” like old permissions lurking in the system. Making it a habit to update permissions immediately helps avoid that all-too-common scramble when someone accidentally accesses sensitive data they shouldn't.
Scheduled checkups on security settings don’t have to be a huge hassle, but they can save you from headaches down the line. A simple calendar reminder each quarter can help keep things on track, and for major changes, consider getting a second set of eyes from your team to make sure nothing is overlooked.
While you’re giving your security settings a refresh, don’t forget to check for any compliance updates that may have rolled out. Staying compliant not only keeps your data secure but also helps you avoid those “friendly reminders” (a.k.a. fines) from regulators.
5. Inspect and replace hardware
Network devices age like everything else—sometimes gracefully, sometimes...not so much. While your router might not throw a retirement party, it’ll start slowing down or glitching as it ages. Frequent inspections keep you ahead of these issues and prevent that last-minute rush when an important device fails mid-project.
A quarterly inspection is usually enough to spot trouble early. Check for things like:
- Overheating
- Odd noises
- Slower performance
If a device seems to be struggling, it might be time to think about an upgrade sooner rather than later. And as for replacements, network hardware generally lasts around three to five years, though devices in busy areas may need updates sooner to keep up with demand.
Keep an inventory of all network devices, including their purchase dates, to make tracking replacement timelines easy. It might not sound thrilling, but planning for replacements ahead of time will save you a lot of problems down the line—and help keep the budget in check.
Things to keep in mind:
- Inspect hardware quarterly, keeping an eye out for heat, noise, or performance drops
- Keep a simple inventory to track each device’s age and condition
- Plan for replacements every three to five years, with wiggle room for high-demand devices
6. Backup critical data
Data loss is every IT team’s worst nightmare—nothing puts a damper on the day quite like realizing important files have vanished. The best defense? Consistent backups, and not just any backups, but ones that are actually useful when it’s time to restore.
Practical advice for backing up important data includes:
- Schedule daily backups for critical data to avoid losing recent work.
- Store backups in multiple locations for added security.
- Set automated backups to run on a fixed schedule, so it’s one less thing to remember.
- Test restore procedures every quarter to confirm that data is accessible and intact.
- Encrypt backup data to protect sensitive information from prying eyes.
Backups are an insurance policy you’ll be glad you have when life throws a curveball. You can also consider automating the whole thing with tools that’ll back up data on a set schedule, so you’re always a step ahead without lifting a finger.
7. Check access control lists
Keeping access control lists (ACLs) up-to-date tells your network who to let in and who to keep out. No one wants old employees—or worse, random users—accessing sensitive data, right? Periodic reviews make sure permissions match current roles, cutting down on security risks and those dreaded “access denied” issues for legitimate users.
Review access rights quarterly
Even though quarterly checks might sound frequent, it’s surprising how fast roles can change. A quick review every few months helps catch any outdated permissions, especially for people who’ve moved departments or left the company entirely.
Revoke outdated permissions ASAP
Don’t wait for the next review if someone’s role changes. As soon as someone shifts roles, update their permissions. This avoids confusion and keeps only the right people with the right level of access.
For an added layer of protection, consider running a full audit of access lists once a year. It’s a great way to catch any sneaky permissions that might have slipped through the cracks—and an easy way to confirm everything is in order. Keeping the access list clean and accurate boosts security and saves you from fielding access complaints.
8. Conduct vulnerability assessments
Vulnerability assessments are routine check-ups that catch issues early—the ones that save you from future migraines. These scans give you a sneak peek into any weak points in your network that could be just waiting for an attacker to exploit. Regular scans not only keep things secure but also help you sleep a little better, knowing your bases are covered.
Run scans monthly
Run vulnerability scans each month, or more often for networks handling high-security tasks. Routine scans catch issues early without filling your inbox. Plus, security threats evolve, so a monthly scan is like giving your network a routine pulse check.
Prioritize vulnerabilities
Not all vulnerabilities need the same level of attention. If the scanner flags something as high-risk, move fast. Address those within a week, especially ones that could lead to data exposure. The smaller stuff? You can queue it up, but don’t ignore it too long—small issues have a way of becoming bigger.
Document your fixes
After each assessment, keep a record of what you’ve addressed. It’s a great reference for audits, and you’ll thank yourself later if similar issues pop up. Routine assessments and quick action on high-priority issues keep your network ready for anything.
9. Perform troubleshooting and diagnostics
Diagnostics might sound technical, but really, it's just about spotting anything that’s a bit off. It’s like a network’s daily checkup—catching problems before they turn into network emergencies. A little routine troubleshooting can save you from facing a mountain of issues later on.
Check network logs daily for error patterns
These logs are a goldmine for catching warning signs early. Errors, dropped packets, unusual traffic spikes—it’s all right there, just waiting for you to spot the trends. Make it a habit, and you’ll stay a step ahead.
Run diagnostics quarterly to catch hidden problems
Quarterly diagnostics dig a little deeper, revealing the issues that aren’t obvious day-to-day. If you’ve ever had a router on the fritz that suddenly gives up the ghost, you know why this matters. Running these checks helps identify equipment nearing its end-of-life date or a setting that's gone rogue.
10. Build an IT network maintenance plan
A solid maintenance plan is like your trusty GPS—it keeps you from wandering aimlessly and helps dodge those “unexpected” breakdowns. It doesn’t have to be complex; a simple, consistent schedule works wonders for keeping things in check.
Set device replacement timelines
Most network hardware, like routers and switches, tend to perform well for about three to five years. While it’s tempting to keep something that still works, older equipment is more likely to cause issues, especially when compatibility with newer devices or security updates drops off. We recommend penciling in replacements around the four-year mark to stay ahead.
Establish a routine
Some things benefit from regular, quick check-ins. Quarterly tasks might include:
- Firmware updates
- Security audits
- Performance monitoring tweaks
Annual tasks could involve:
- A more thorough check of network hardware
- An in-depth security review
- Evaluating bandwidth needs
Plus, an annual review of the plan itself can help ensure it stays relevant as your network grows. Part of a good plan is thinking ahead. Today’s network might run fine, but what about next year? Regularly evaluate if it can handle new users, tools, or data demands. It’s a bit like planning closet space—things tend to grow faster than you expect.
Add a budget for replacements and upgrades
Budgeting can feel like extra work, but it’s a lifesaver when it’s time to swap out aging equipment or add capacity. Setting aside a bit each quarter makes those “planned” replacements a little less painful, and you won’t be scrambling for funds when the time comes.
Create a checklist
A quarterly checklist can include routine updates and security reviews, while the annual one could cover replacements, audits, and any deeper dives into system performance. Keep it simple and realistic—you don’t want to be juggling so many tasks that it feels overwhelming.
Planning isn’t glamorous, but with a clear maintenance roadmap, you’re giving your network a longer, healthier life. Plus, there’s peace of mind in knowing you’re prepared rather than just reacting.
Who conducts network maintenance?
Network maintenance can be handled by in-house IT staff or outsourced to managed service providers (MSPs). For teams without an in-house IT squad, working with an MSP brings expertise without the full-time commitment. It’s like having a network mechanic on speed dial—they handle the upkeep, so you don’t have to get under the hood yourself.
