@Fredtx said in Help Understanding LAN test Speed Results: I ran a LAN Test speed using from a client to a server, which are both in the same LAN as it's a small dental office network. The results are showing 67.88Mbps (Writing/Upload) and 405.51Mbps (Reading/download). I don't know what their physical infrastructure is as I work remote, but I'm sure it's 1Gbps Ethernet. If that's the case, does this test result indicate there's an issue, with the huge difference between upload and download, all in the local LAN? That the test is labeled writing / reading.... then yes, you're expected to be testing a lot more than the network and a big difference would be expected.

@scottalanmiller said in First Look Ubiquiti Unifi UXG Pro: The new, unreleased Unifi UXG Pro just arrived here at the NTG Dallas offices. Woot! It's dual power supply, dual WAN, dual LAN, touch screen LCD and up and running! More details as we get to play with it. DAMN IT!!!

@EddieJennings said in MacVTap Modes: One option I didn't see in the redhat doc was openvswitch. Don't they support it? The link I posted was for RHEL 6. I just now saw that RHEL 8's documentation is online. I glanced through it and didn't see that mentioned. I'll read it more closely tomorrow. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_virtualization/configuring-virtual-machine-network-connections_configuring-and-managing-virtualization There's no mention of openvswitch anywhere in that document. I am aware of XenServer and XCP-ng uses it by default. So its possible RHEL just prefers using macvlan/macvtap instead of openvswitch.

@JasGot said in DHCP Question...: I guess I am going back subnet school. I found it, it's in the faded greyed out area under the red rectangle.

@wrx7m said in Tool for Finding Rogue DHCP: Ran into this about 12 years ago. A guy on the dev team decided to setup his own DHCP server. Screwed up all sorts of stuff. Can't remember for sure what we did, but I think after we realized that it wasn't actually an issue with our known DHCP servers, we decided to talk to the dev team and found out that is what he had done. It amazes me how many people just don't think about it - they have a problem, they think they know how to solve it, and just slap something onto the network.

@Romo said in Unifi USG VPN from Behind NAT Firewall: Also add the changes to a config.gateway.json file in the controller to changes directly made on the USG don't get deleted on next provision. One reason I hate these units.

@brandon220 said in how does this work? Modems/IPs/PCI Scans: @JaredBusch example also is great for home use if you have IoT devices. I have an ERL behind a cable modem and this keeps everything I want separated from my normal LAN. That is a good way to practice this for business use

@JaredBusch said in Datto AP60: @WrCombs said in Datto AP60: @JaredBusch said in Datto AP60: @Dashrender said in Datto AP60: Of course, they are basically useless in this setup, because the APs are on a non internet connected network. No, they are not. @dbeato has clearly stated it works offline once programmed. Yes @NDC mentioned a rare condition where it failed. None of that matters. This unit is not going out to the restaraunt. He only needs the fucking thing to configure the tablets in the office. The restaurant will be providing s the wifi for the production closed network. this People are fucking too stupid to remember from the top of a thread to the bottom I swear. Anyway, you can use the Datto just like I outlined for the UniFi. Assuming you can get it programmed by someone. @dbeato Private messaged me and if that's the route we take he said he'd help .

In theory, you could even update the firmware on the UAP, in the future, by pre-downloading it on a device that presents it via a URL and then join that device to the aloha network. But that would be excessive amounts of work. Possibly the app could do it on an iPhone/Android device with LTE that is also joined to the aloha wifi.

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

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?

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!!!

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.)
