The setup

Cable modem 30mbit/3mbit

Cisco Linksys router WRT160N v3

2 notebook computers

The issue : Wireless speeds (both using wireless and doing speed test from ISP speedtest page)

Notebook(A) can achieve max speed

Notebook(B) often stops in the middle of the test or oscillates between 3mbit and 10mbit (really unstable)

At first I thought it was my channel. I tried them all. Channel 5 gives perfect results on notebook(a) and awful results on notebook(b) which makes no sense at all...

Both notebooks are right beside each other

Both have fresh windows installations without any software doing background transfers

On notebook(a), doing a ping loop on my router gives constant 1ms-5ms

On notebook(a), doing a ping loop on my router while doing the speedtest gives constant 5ms-15ms

On notebook(b), doing a ping loop on my router gives an unstable 10ms-35ms

On notebook(b), doing a ping loop on my router while doing the speedtest gives an unstable 70ms-800ms (huge fluctuations)

I've tried changing the width from 20hz to 40hz.

I've tried all the channels

I've tried Mixed, G-only and N-only

I've tried increasing the TX power (from 71 to 100)

Microwave is off.

Phones aren't in use

Cellphones are in airplane mode

There isn't alot of other wireless signals in my surroundings (3-4 max at a very weak signal strength)

I'm REALLY out of ideas. notebook(b) works GREAT with a wired connection.

Also this recently started occuring. It was working great a couple weeks ago.

Wow I tap myself on the back on this. I just found out that the culprit of all my headaches is BLUETOOTH.

After either disabling the device or removing the ability to devices to connect my PC, the problem vanished.

I now max my bandwidth easily. I wonder how it was affecting my wireless signal. Certainly not "outside" the notebook because notebook(a) was not affected by this. It was messing it up internally.

OH WELL :) Thanks for the replies guys

oh well you solved this! good job. LOL

but for future ref...:

have you tried a USB adapter? also please try redoing the wlan drivers... use something called driver fusion to completely wipe the drivers and then reinstall using the latest ones from the mfr and see if this helps.

    • Microsoft Edge gets tons of security features, including AI model that can see your screen

      By Usama Jawad96 · Posted

      Microsoft Edge gets tons of security features, including AI model that can see your screen by Usama Jawad Microsoft Edge may not be the most popular browser out there, but it does receive quite frequent updates that sometimes bring surprising new features and axe others that are not as popular. Now, Microsoft has detailed some of the new security enhancements that it has introduced in Edge for Business, typically used by commercial customers. Microsoft has emphasized that security features are baked into Edge for Business and offer native integration with security and governance tools like Defender and Purview. Browser sessions are governed by default on managed devices but can also be governed through dedicated work profiles on unmanaged devices. An important aspect in this area is controlling the use of shadow AI. We have talked about this before, but it essentially restricts employees from using unsanctioned AI apps through data loss prevention (DLP) policies, with Edge redirecting them to trusted AI services like Microsoft 365 Copilot. This feature, available as a pay-as-you-go (PAYG) license, ensures that confidential data never exits AI boundaries set by your organization in Purview. Additionally, Microsoft also has strong DLP policies for contractors. Contractors leveraging a Entra ID-joined work profile provisioned by their contracting company on a device managed by their actual employer can be restricted from downloading files locally. In such scenarios, the file is saved on the contracting firm's OneDrive rather than being downloaded locally. Another useful Edge security feature disallows copying and pasting from unmanaged locations and apps. Similarly, DLP policies can be configured at a granular level to restrict screenshots or downloading of files from certain locations. In the same vein, IT admins can block the installation of extensions, hosted apps, themes and scripts, and control if users can install extensions from external locations. They can also enable the installation of specific extensions and allow users to request access to certain extensions, so that they can be managed on a case-by-case basis. Finally, Edge for Business now has an on-device AI model that uses computer vision to see what's on your screen and block potentially malicious content immediately. This does not rely on site reputation, as it simply monitors what is being displayed on your screen, which means that it is effective against malicious content that takes over your screen and employs scareware tactics. Since this is an on-device AI model, it does use your system's resources, so it's enabled by default only on devices with at least 2GB of RAM and four CPU cores. You can find more details in the Microsoft Mechanics video here.
    • Linux 7.2's first release candidate gets off to a good start

      Could you come up with a slightly less depressing background for Tux instead of that gray gradient? Doesn't have to be cheerful, just less of a downer...
    • Linux 7.2's first release candidate gets off to a good start

      By zikalify · Posted

      Linux 7.2's first release candidate gets off to a good start by Paul Hill Credit: Larry Ewing It has been a few weeks since the release of Linux 7.1, and in that time, the Linux 7.2 merge window has been open, where developers can submit their features and patches ready for the upcoming release. That window is now shut, and the release candidate phase has begun so that new features can be tested and further fixes applied. According to the founder of Linux, Linus Torvalds, this week’s release candidate looks “reasonably normal”. Although we are super early in the release candidates, this is a good sign as it makes it more likely that an eighth release candidate will not be needed. Torvalds even mentioned that the update’s stats are only larger than they really are because there was another AMD header drop with a third of the patch just being AMD GPU register definitions, which aren’t big changes but make the code contributed look larger overall. In addition to this, he noted that just over half the patch is drivers, even when excluding the AMD register dump. The rest of the changes are spread out over architecture updates, tooling, documentation, and core kernel updates. In the next week, Torvalds says that he will be chilling out, taking the week “mostly off”. Despite this, he will be reading emails and keeping up with things, so if he is slow responding, now you know why. He said he is hoping for a calm week, but we will just have to see if the second release candidate is actually like that. We should expect seven or eight release candidates before Linux 7.2 is released, so expect it around the end of August. If you missed it a few weeks ago, be sure to check out our coverage of Linux 7.1's release.

      Ridiculous claim that the labor cost difference of $6000 annually would increase cost per phone by $200. The employees produce 3 phones per month or what?
