PC: Dell 7060 SFF

SSD: Old Patriot P210 III 512GB

Installation media: up-to-date Win 11 ISO on flsh drive

After I disabled secure boot, it allowed me to do the installation.

I felt it was strange so I checked and found out the SSD is too old, I replaced with a newer WD SSD and enable Secure Boot in BIOS, no problem to do the installation of Win 11.

So, it is the SSD compatible issue.

I did VHS videotape converting from a 3-hour long tape to mp4 today.

Solution: This is a common driver compatibility issue. Please try disabling Fast Startup.

I encountered a HP Officejet 4500 drivers downloading problem from www.hp.ca.

When I search “HP Laserjet 4500 Wireless ” on the model box, it prompt “This is a discontinued model and we don’t provide the drivers any more”.

The alternate way for this kind of issues is Google the drive from HP website forum but be careful not download the “fake” one which includes the virus or redirect to some unhealthy websites.

By default, Telus/Rogers Routers are in AP mode, use as a router , prividing Internal IP addresses to computers and other “Smart” devices in the LAN;

But, when users want to use their own router, they have to set the Telus/Rogers router to bridge mode. By doing this, the users own router can have pubic IP ,for some particular reasons(to “dial in”, to port forwarding some devices to Internet,etc).

In conclusion,Bridge mode disables routing/NAT on the Telus/Rogers gateway and The Telus device acts only as a modem. That means Telus/Rogers assigns the public WAN IP directly to your own router’s WAN port.

Complain: I having to restart after each boot up as on first (cold) start since this update the keyboard on Lenovo laptop does not work. But when I reboot , the keyboard is back to normal.
