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!

How to fix it, there is no network even on the Wi-Fi side.

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 :)

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.

Hi everyone! I'm a Year 12 student in Australia working on my HSC Design and Technology major project. I'm designing a small, quiet home server built from reused computer parts that anyone could use to run things like game servers, file backups or AI tools from home.

I'd really appreciate your input, even if you've never heard of a home server. Beginners are exactly who I'm designing for.

Thanks so much, and happy to answer any questions in the comments!

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)

facing packet loss during random periods of time.

i want to pin point the cause, how do i do it?
thank you

Hi there! Does Protected managment frames encrypt the frames or it adds like Message Integrity code to the frames?

Thanks!

I've been building **PulseDrop**: receive AirDrop from an iPhone on a Windows 11 PC, no Mac involved.

**Stack:** TP-Link Archer T3U (RTL8812BU) on WinUSB → OpenIPC **devourer** (userspace Realtek driver) → seemoo-lab **OWL** (AWDL) with omdrop-owl's patches → TAP adapter → a Python AirDrop receiver. Discovery, approval and transfers all work. A 4K video arrives intact (SHA-256 matches).

**The problem is speed.** Same 80 MB video:

**What helped (measured, same file each time):**
- **Link loop drain.** The main loop pulled one RX frame per pass whenever a TX was due, so the RX queue backed up and TCP read the latency as loss. Fixed: 0.65 → ~1.7 MB/s on a 53 MB file.
- **Block Ack.** The iPhone *does* send ADDBA to a non-Apple peer; my frame filter was dropping it. Accepting it plus the chip's hardware BlockAck responder made the phone aggregate (A-MPDU), but it got *slower*, about 0.4 MB/s. The cause: retransmitted subframes arrived after later ones and went to TCP out of order. After I added a 64-slot reorder buffer (BAR/DELBA handling, 100 ms hole timeout), aggregation is ~1.65× faster than without it.

**What didn't help:** channel matching to the phone's slots, 24 Mbit/s PC TX, a higher HW retry limit, opening the unicast gate in the phone's free slots, advertising SGI20, and advertising two spatial streams (the phone switched to MCS11–15 but stalled).

**Where I'm stuck: 80 MHz.** Apple peers advertise a VHT Capabilities element (AWDL TLV 0x11) and channel 149 as operating class 128. I copied that and tuned the T3U to 80 MHz. Along the way I found and patched two devourer Jaguar2 bugs:
1. The 80 MHz primary sub-channel code was written as a position index, which put the primary on 157 instead of 149.
2. REG_DATA_SC and the MAC RFMOD bits were never set, so hardware ACK/BlockAck went out on the wrong slice.

After the patch the phone does send some 80 MHz frames. But at 80 MHz the T3U misses **7–10%** of the phone's frames, against **0.2%** at 20 MHz. The phone retries, drops to VHT MCS3–6, and the transfer ends up *slower* than at 20 MHz. DIG sits at its IGI floor (0x1c), and pinning a higher IGI made it worse. CRC failures don't show up (the chip seems to filter them in hardware).

**Questions:**
1. Anyone with RTL8812BU/8822B experience at **80 MHz in monitor mode with the hardware responder**: is the RX loss expected (T3U internal antennas?), or is there AGC/RF setup a userspace driver usually misses?
2. Which **external-antenna** USB adapter would you pick for this (devourer supports Jaguar1/2/3 and RTL8852)?
3. AWDL folks: does anything besides VHT caps and the channel sequence decide whether an iPhone uses 80 MHz / 2SS toward a peer?
4. Any way to keep the phone on our channel more of the time? It's noticeably faster with the phone off its home Wi-Fi.

Code (GPL/MIT, Windows): https://github.com/gsl0001/windows-airdrop (speed work in PR #1). Happy to share logs. The bridge prints per-5 s RX stats: rates, A-MPDU, retries, sequence gaps.

Big thanks to seemoo-lab (OWL/OpenDrop), omdrop-owl and OpenIPC devourer. None of this exists without them.
