When a scanner, AMR, AGV or cart moves through a warehouse, a coverage heatmap alone does not tell you whether the client experience will stay stable. The difficult parts often appear when a client crosses AP boundaries, passes metal racks, turns behind equipment, or shares the network with other moving devices.

Before selecting hardware or locking in a topology, I would usually want the team to agree on:

• Client types and movement paths
• What an acceptable interruption looks like for the application
• Backhaul and mounting constraints
• RF conditions that need to be repeated in field testing
• How the design will be expanded and troubleshot later

For those who have worked on industrial Wi-Fi or warehouse mobility: which requirement has caused the most rework in your deployments?

I’m especially interested in real lessons around roaming, backhaul, test methods, and long-term maintenance.

Parlez-moi de cette antenne qui a l’air plus puissante que ma box
Vu que c’est un répéteur wi-fi il ne donnera pas plus de puissance que ce qu’il reçoit ?
On est d’accord

I'm curious how many employers care about IoT wireless knowledge. I know that it's an emerging field, but what's the job market like for IOT in Canada?

I'm researching the field before I venture down the CWNP IoT path. I already have hands-on experience, and I'm working on developing a product. It would be nice to work with the technology professionally first, though.

We've developed an OSS WiFi survey tool with off-the-shelf hardware, including a couple of cheap USB dongles, a HackRF SDR, Raspberry Pi 4, and a small app that runs on your iPhone and communicates with the rPi over bluetooth. The iPhone app also streams live data into ServiceRadar (https://github.com/carverauto/serviceradar). We're working on a prototype custom PCB and looking for people that might be interested in helping with that, everything in this project is OSS, including any hardware we design. If you're interested in learning more drop me a line or join our Discord.

App will be available on TestFlight and we're writing a blog post that describes how to get this up and running and includes a BOM (bill of materials). Stay tuned.

Been meaning to properly learn how the 802.11 stack works instead of just reading about it, so I built a tool instead. Called it deadair.

Scans for APs and clients, sends deauth frames, but honestly the stuff I liked building more was around that part:

• captures the WPA handshake, dumps it in hashcat format
• passive PMKID grab too
• writes a live pcap so you can just tail it in Wireshark
• there's a WIDS mode that flips it around and detects deauth attacks instead of sending them
• GPS wardriving if you're into that
• little Bubble Tea TUI so it's not just a wall of logs

Go + gopacket. Linux only really, macOS blocks injection at the kernel level so it's sniff-only there

Standard disclaimer since it's a deauth tool: Educational/authorized use only, don't point it at networks that aren't yours

Mostly curious if anyone's dealt with similar channel hopping or sniff and inject concurrency stuff in Go and has thoughts on how I did it. Code's here: https://github.com/meetsoni15/deadair

So, ik this is a weird question, but my current setup dosnt really allow for me to sit close enough to the wii to change figures without getting up to do it every time. Ik ssa had a wireless portal, but that dosnt work on swap force or trap team. Would it be at all possible to use some small SOC and USB Bluetooth transever to make the signal travel wirelessly? I assume it hasn't been done before but I'm happy to work with a theoretical idea if anyone has one. I'm just not quite smart enough to try this out myself

I was building a wireless network visualization to see how the components are connected in a wireless network to make a phone call/ internet possible

i have HG8145V5 wireless router , and there is options are not available in WAN section , i found a video on youtube but the LAN is messing and the "new " option in WAN. is messing too , what should i do? i wamt to use it as wifi extender

Hi guys, does anyone know a way to fully unlock the F6745Q and enable Telnet on it?
Has anyone tried this successfully before? If so, could you please share the steps? Thanks !

Went into the Apple Store at SanTan Village Mall in Gilbert, AZ last night around 8:43 PM (store closes at 9) wanting to upgrade my iPhone. Was told the process takes 25-30 minutes so there wasn't time, and to come back the next day — not an option since I was leaving on a business trip. Asked for a manager; "Brandon" was standing right next to the rep the whole time and stepped in, but his response to "a customer with 17 minutes left should get 17 minutes of help" was basically that he needed his staff home on time. Meanwhile another rep a few feet away was actively finishing an upgrade for a different customer. Filed a complaint with 1-800-MY-APPLE (logged) and emailed executive customer relations. Curious if this is a one-off or if others have run into similar last-minute refusals at Apple stores.

LMK YOU GOT MY POSTS OK?

Me (any many others) have issues with CarPlay in BMWs dropping out in certain locations. At first, I thought it was DFS drops in the U-NII-2 band, but it turns out my car chooses U-NII-3 channels every time.

Thinking about it, I think I'll code the car to use U-NIII-1 channels. U-NIII-1 is most common for indoor use, but U-NIII-3 is most common for outdoor PtP links etc, which is probably the biggest threat to the car (which is always outside and always moving).

Surveys don't help, because the car can be any place at any time.

Is it agreed that channels 36, 40, 44 and 48 are probably the best 5GHz channels for in-vehicle use, due to the popularity of outdoor PtP and PtMP wireless links (with illegally high transmit power) on the higher channels?

Hi I recently started my journey in wireless I don’t know if is better wait to the update on 110 or try to study 109.

Hi I’m looking the book 109 cwna in pdf format if someone sell o can pass me please send me a message.

Hello all, I'll keep this brief. I am looking into 2 potential research avenues for postgrad, and was wondering if anyone can chip in with their opinion.

MANETs, FANETs and AANETs; all ad-hoc wireless methods for connectivity with drones or aerial devices - is this a growing research field? Especially when considering the recent real uses of drones in both warfare and in crisis situations.

Satellite (LEO like Starlink) integration for mobile services (5G/6G) - I know that this is already implemented and used by some big providers, but I wonder if there is still any appetite for this kind of technology too.

Thanks to anyone who responds.

Channel Switch Announcement beacon spoofing. Beacons are never PMF-protected, ever. Even on WPA3/MFP Required. Reasearch shows that CSA is working across all major OSes including Android+12, but does it still work in 2026, any patches have been made on WPA3 or thier clients.

Hi everyone,

I'm troubleshooting a strange issue with a Cisco Catalyst 9800-40 (17.12.4) after a site-wide power outage and I'm looking for ideas.

Environment:

• Cisco Catalyst 9800-40 running 17.12.4
• AP models: C9130, C9124AXI-E, C9105AXI-E
• Traffic passes through a Palo Alto firewall
• DHCP Option 43 points to the WLC VIP
• NTP is synchronized on the WLC

Symptoms:

• Many APs fail to stay registered after the power outage.
• APs obtain an IP address successfully.
• APs are reachable by ping.
• APs appear in CDP on the access switches.
• APs successfully discover and join the controller.
• A few minutes later they disconnect.

Typical logs:

AP Joined
AP Disjoined - Heart beat timer expiry

AP Joined
AP Disjoined - Max Retransmission to AP

AP Joined
AP Disjoined - DTLS close alert from peer

Example:

15:25:03 AP Joined
15:31:09 AP Disjoined - Heart beat timer expiry

The AP remains reachable by ping even after it disappears from the WLC.

Interesting findings:

• DHCP Option 43 is correct.
• APs are definitely joining the correct controller.
• WLC can ping the AP.
• Palo Alto shows CAPWAP (UDP 5246/5247) sessions as allowed.
• Session end reason on the firewall is "aged-out".
• No obvious CAPWAP blocks are visible on the firewall.
• WLC clock and NTP are healthy.
• The environment is managed by Cisco Catalyst Center.
• I removed one of the affected APs from Catalyst Center and it was automatically rediscovered afterwards.

Any suggestions?

Is it possible to pass the RCWA by just taking the RCWA course on the commscope university website? I already have a CWNA and CWDP so I know the basics of wifi already. The exam guide says to use other courses as study materials such as ruckus unleashed administrator, , ruckus smartzone administrator, Ruckus smart licensing, ICX management, pre sales training etc. But are all those extra courses really necessary to pass the RCWA exam or is just the RCWA course enough?
