[Bug] in Airtel Xstream fiber

The Bug: After any reboot, the 2.4GHz speed hard-caps at 1-2 Mbps. The web UI settings do not visibly change-it still shows my configured AX/Wi-Fi 6 settings-but the actual performance tanks. 5GHz is unaffected. Farmware version is AOT5221ZYR2.28 The Workaround: I have to log into the web UI, change the 2.4GHz standard to b, apply, and then change it back to ax. This restores full speed until the next reboot. What I Tried: Edited config.xml to permanently fix the initialization. Tried forcing (ax, n,ax, bgnax), locked 20MHz, and disabled PMF/DFS/Bandwidth Coexistence. Nothing prevents the post-reboot speed drop. Has anyone found a permanent fix, or should I demand a different router model?

​How to Find and Delete Patch Bundles to Free Up Storage

Where is the 'Patch bundles' category located so I can delete a saved bundle? I only see the 'Saved APK' section, but the storage graph shows that 'Patch bundles' is taking up 210 MB. How do I clear those?

Does anyone use Zoiper or another app to make VoIP calls with a landline number?

I have an AOT5221ZY fiber router, but after completing the configuration, Zoiper still doesn't show a green signal. The XML file only contains IPv6 data, and even after modifying it, neither Zoiper nor any other SIP softphone works. What should I do to solve this issue?

Constant Subwoofer Hum & Extreme IC Overheating on 2.1 Amp Board

am troubleshooting a standard 2.1 channel audio amplifier board (12-0-12 dual-rail, TDA2030s for satellites, D2050 for the subwoofer, F4558 crossover). It suddenly developed a loud, constant hum on the subwoofer channel that does not change intensity when adjusting the volume.

​If the speaker is disconnected, the chip gets hot, but the moment a 4-ohm speaker is connected, the IC pulls massive current and gets blisteringly hot almost instantly.

​Diagnostic Tests i do

​Power Rail Check: Measured across Pin 3 (-Vcc) and Pin 5 (+Vcc) on the subwoofer IC. Getting a healthy ~30V total swing (roughly -15V and +15V). Main 1000µF 25V filter capacitors show no visual signs of bulging or leaking.

​DC Offset Test: Measured between Pin 3 (-Vcc) and Pin 4 (Output) on the original D2050 and got exactly 15V. This confirms Pin 4 is sitting at 0V relative to the main ground, so there is no direct DC short to the rails.

​IC Swap: To rule out internal failure or oscillation inside the D2050, I completely desoldered it and swapped in a spare UTC2030A (properly isolated with a thermal pad on the heatsink).

​Swap Result: The exact same symptoms persisted with the new IC. It produces the same heavy hum and instantly overheats when the speaker is connected.

Please guide me what i do next

Is there any way to get full speed on the 2.4 GHz band in this congestion?

Whenever I run a speed test on my 2.4 GHz band, I only get 1 to 2 Mbps download, though the upload speed is fine. On the 5 GHz band, I get full speed for both downloads and uploads, but its coverage is very limited. Is there any way to get full speed on the 2.4 GHz band without buying an external mesh router or extra equipment?

PCB won't power on: Multimeter shows direct short between VCC and GND, but no visible burn marks.

Hey everyone, hoping you can help me out with a headache of a board today.

It completely refuses to power on. The frustrating part is that there’s no magic smoke, no burn marks, and visually, everything looks absolutely pristine.

I scratched off a tiny bit of the green solder mask right next to the DC barrel jack to get a good probe on the bare copper. My multimeter is just screaming at me in continuity mode—I've got a dead, solid short between the main power rail and ground.

I probed the main input protection diode (D7, an SS14). In-circuit, it's reading about 145 one way, and 1445 the other way.

so what i do and how to fix this issue.....

Thanks!

Need help: Massive EMI / Inrush current from a 12V car window motor is freezing my Arduino Uno, despite using isolated power supplies.

I’m building an automated wire cutter. I use a Nema 23 stepper to feed the wire, and a heavy-duty 12V car window motor connected to a mechanical relay to actuate the cutting scissors. I'm using an I2C 16x2 LCD for the menu and an IR sensor for limit detection.

​The Problem:

Whenever the relay fires to turn the window motor ON or OFF, the massive inrush current (and resulting EMP/EMI) scrambles my Arduino Uno. The logic gets completely disturbed—sometimes the board hard resets, and other times the I2C LCD screen just freezes and the machine gets stuck.

​If I disconnect the window motor from the relay, the relay clicks on and off perfectly, and the code runs flawlessly. The code and logic are solid; this is 100% a hardware/EMI issue.

​My Hardware Setup:

​Controller: Arduino Uno

​Motors: Nema 23 (Stepper) & 12V Car Window Motor (Cutter)

​Power Supply 1 (For Motors): 12V 10A SMPS

​Power Supply 2 (For Uno): Completely separate 5V wall charger (USB)

​Switching: Standard blue 10A mechanical relay modules

​What I Have Already Tried (That didn't work):

​Completely Isolated Power: The Uno is powered by the wall plug. The SMPS powers the motors. The Grounds (GND) are 100% separated and do not touch.

​Cascaded Pilot Relays: I tried using the Uno to trigger a small pilot relay, which then switches 5V to trigger the main heavy-duty relay. The EMI still bypasses the air gap.

​Opto-isolation: Removed the JD-VCC jumper on the relay module and powered the relay coil with the separate power supply.

​Hardware Pull-ups: Added a 10k resistor holding the RESET pin to 5V to prevent random reboots.

Meta just dropped a paid "WhatsApp Plus" subscription. Morphe devs, we need you to tackle this stupidity!

Wtf is Meta thinking? They are officially trying to push a new subscription model for WhatsApp, and it's ridiculous. If you look at the screenshot I attached , they are asking for ₹79.00/month just to unlock features that shouldn't be premium in the first place.

I hope morphe releases patch for WhatsApp..

Loving the new Tablet UI on my phone.

I've been using the Tablet UI on my phone, and honestly, I like it much more than the original mobile layout.

The larger video thumbnails, cleaner interface, and overall viewing experience feel much better to me. It makes browsing YouTube more enjoyable, even if it leaves a little extra spacing between videos.

Is there any way to spoof my Galaxy F15 5G so Samsung Members recognizes it as an eligible device for the One UI Beta?

I have a Samsung Galaxy F15 5G, and it doesn't seem to be eligible for the One UI Beta program in the Samsung Members app.

I'm wondering if there's any method to spoof the device identity so that Samsung Members thinks it's an eligible model (like a Galaxy S23 or another supported device) and allows beta enrollment.

Has anyone successfully done this? Does changing the device fingerprint or model information work, or does Samsung verify the actual hardware or IMEI on its servers?

I'm only looking to understand how the eligibility check works and whether there's any known method to bypass the device restriction.

How can I bypass this country restriction? Is there any setting in youtube Morphe ?

Whenever I click a YouTube chat/message link , I get this error:

«"Messaging on YouTube isn't available in your country."»

This happens every time I try to open a chat link.

Has anyone else experienced this? Is there any setting, hidden toggle, or feature in MorpheApp that can bypass this restriction, or is this completely controlled by YouTube?

Any help or suggestions would be appreciated.
