OK late to the thread. We use a cheap travel router for this purpose. GL.iNET GL-MT300N think we paid $25 for it. Supports up to 4 SSID's and can do VLAN's though we only use 1. We can actual do wifi to wifi bridging with it. We use it for these wifi Sapling clocks that need to connect to a pre-provided WPA2-PSK ssid for initial setup.
This is the newest version: https://store.gl-inet.com/collections/travel-routers/products/gl-mt300n-v2-mini-smart-router
Can get these on Amazon now for $25

Your DHCP range isn't close to being full, is it?

Man, I wouldn't think that would prevent a renewal.

It does. Depends on race conditions, but it definitely happens.

I guess I need to re-read up on the DHCP process - I thought (at least with Windows) that the client machine did a check at the 50% timeframe and renewed then, thereby never actually reaching an expired state. But that was 20+ years ago when I read the MS docs on it... so I could have a faulty memory.

It does, but machines powering on and off and such can disrupt that process.

uh, what? Sure, now if a machine is off, and the half way point, or the full expire time hits, sure, when the machine comes back online - it has to basically start over...

The OP says the machine is loosing it's IP what appears to be overnight. OK, so let's assume the lease expired while the computers were in powersaver mode, or simply off. I would expect them to be turned on and simply go through a DHCP request - but the OP says a reboot it required to get back on the network. so something isn't working from the client side.

So the NIC has been updated and that didn't solve it.

Any chance the switch could be the culprit? Are there updates available for the switch?

Roflol

I used to manage a Full Tolerance Infrastructure.

2 Devices of Everything (Routers, Firewalls, Edge Switches, Core Switches, Access Switches, etc)
2 Internet Providers
2 Private Circuits

Network Documentation is very very important, for Network Admins is a must, because for example a new team member joins, this information will be useful to acknowledge the network infrastructure.

I have experienced that T3 (DS3) collapses (saturates) once you reach 40 Mbps, even rate is up to 44 Mbps.

@Pete-S Very true, in IT temporary becamos forever... that is a LAW!!!

But I'm literally 100% confident given your description, that you are perceiving it as people using "cell phones" to replace VoIP, and not realizing that it's standard VoIP softphones being deployed onto mobile computing devices that are often, but not required to be, cell phones.

We have cisco everything and I was told it was too expensive to have softphones on our cell, we instead must have a separate cell phone. I doubt that, but who knows.

And yet it wasn't too expensive to have Cisco... suspicious.

yep, agree!

@melvinsilva said in Optical Fiber Connectors - CompTIA Network+ N10-007 Prof. Messer:

@mary It depends on what you have, some Cisco Switches came with GBIC others (now in time) come with SPF.

And now SFP+

(SPF is sunscreen levels, SFP/SFP+ are the adapters.)

This type of cable Im refering to.

@JaredBusch said in Optical Fiber - CompTIA Network+ N10-007 Prof. Messer:

The point was that it is cheaper to buy pre-terminated fiber in the lengths needed instead of buying fiber and getting it terminated.

Not that does not apply universally. It does apply for most office buildings.

Where he is, I have random conversations with people who are like "Oh yeah, I trenched across town myself." Things you never hear here. There is actually a lot of self termination, lol.
