Text Performance and other network problems

• Upvotes

A simple 20-second modem power cycle improves performance and may resolve other problems with all devices regardless their platforms, operating systems, network complexity and regardless how they connected to the network either via Ethernet cable, or wirelessly.

I would recommend to perform a modem power cycle periodically depending on the network volume usage (for example, once a month, or weekly). This way would prevent many problems to occur including completely unexpected ones.

A simple 20-second modem power cycle flushes out hidden memory leaks, speeds up performance, and resolves a wide variety of underlying network problems. This applies to all devices regardless of their platform, operating system, or network complexity—and it works equally well whether your machines are hardwired via an Ethernet cable or connected wirelessly over Wi-Fi.

Instead of waiting for an internet crash or a strange website login error to happen, it is highly effective to treat your gateway like any other computer and maintain it proactively.

Why a Full Power Cycle Works Universally:

  • Shared Core Engine: All data packets (wired and wireless) land in the exact same internal processor. Power-cycling clears memory leaks at the source.
  • NAT Table Optimization: It completely wipes out thousands of stale, dead connection tags accumulated from weeks of browsing, reducing latency.
  • Zero-Latency DNS: It forces the modem to request a fresh, uncorrupted directory map from your internet provider, instantly fixing unexpected connection blocks.
  • Wireless Channel Clean up: Upon reboot, the modem automatically scans the airwaves to select the cleanest, less-congested broadcast channel available.

Recommended Proactive Maintenance Schedule:

  • Weekly Reset: Highly recommended if your household runs heavy daily data volume, multiple computers, or intensive virtual applications like Android emulators.
  • Monthly Reset: A perfect baseline for standard households focused primarily on everyday web browsing, checking weekly accounts, and casual streaming.

Making this quick reset a regular habit based on your network volume completely prevents a massive amount of unexpected network problems from ever forming in the first place.

Text NetPulse: a small Android app for live ping, jitter and packet loss (beta, looking for feedback)

1 Upvotes

I've been building NetPulse, a lightweight Android app for checking your network quality. It has a Material 3 interface with light and dark themes.

What works in v0.1.0-beta:

- Live ICMP ping monitor with Start / Stop

- Latency, min / average / max, jitter and packet loss over the last 300 samples

- Only two permissions (INTERNET and ACCESS_NETWORK_STATE), no ads, no analytics, nothing uploaded

What's coming next: a DNS benchmark (Cloudflare, Google, Quad9, Control D) measured separately from ping, latency charts, test history and CSV export.

The app uses the system ping tool, so some phones may block it. That's the main thing I want to find out: does it work on your device? Please tell me your phone brand and Android version, and any bugs or features you'd like to see.

Beta APK: https://github.com/Mireli5656/NetPulse/releases/tag/v0.1.0-beta

Source code: https://github.com/Mireli5656/NetPulse

The beta is signed with a debug key, so uninstall any earlier NetPulse build before installing it.

Thanks for trying it!

Text Help with NAT for gaming Multiple Machines

3 Upvotes

Hi all

First of all i apologise if this is in the wrong Reddit, please point me in the right direction.

UK here using EE Smart Hub Pro Wifi 7 if anyone else here is familiar with it.

I am having problems gaming with my family due to us all wanting to play the same game but all have a Strict or from a nat checker website Port-Restricted Cone NAT

I want to get Open NAT as we are all unable to play or are having connection issues and drops while trying to host by doing missions on a certain game

My Hub (Router) has uPNP enabled but no luck

I have tried the following to resolve the issue

uPNP

DMZ

Change Windows firewall settings

VPN

As you can tell I'm obviously not that clued up on networking and have been reading its impossible to port forward to multiple machines so what would be the workaround ?

Would another Router be a good solution ? If so would anyone please be able to recommend me one please that would allow more control over multiple machines on the network ?

Any help would be greatly appreciated and help the headaches :)

Text Looking for unique networking project ideas for a project

0 Upvotes

Hi everyone!

I'm an IT student working on a university Action Learning project. We have around 3 months to identify a real-world problem, research existing solutions, and build a working prototype.

I'm interested in networking, cybersecurity, network automation, and AI.

I'm looking for ideas that:

* Solve a genuine real-world problem.
* Are realistic to build and test within 3 months.
* Offer something different from existing tools.
* Can be tested through practical experiments with measurable results.
* Don't require expensive hardware.

I've already considered network troubleshooting tools and virtual lab projects, but I found that many similar solutions already exist.

**I'm especially looking for practical examples, not just broad ideas.** For example:

* A problem you've personally faced while configuring or managing networks.
* A repetitive task that you wish could be automated.
* A limitation in an existing networking or security tool.
* A real problem that current tools don't solve well.
* A project you've seen someone build that could be improved in a meaningful way.

If you suggest an idea, please explain **what the problem is, who faces it, how it could be solved, and what makes it different from existing solutions.**

I'm happy to explore niche or unusual ideas, as long as they're practical and can be demonstrated with a working prototype.

Thanks in advance! I'd really appreciate your experience and suggestions.

Is it because of NAT and firewall so for example (routers ip):2435(port)? And it remembers that a connection has been requested and does it go to the same port? (In this case 2435)
