Ubiquiti UniFi U6-LR

Ubiquiti sent me two of their newly released Unifi Access Point WiFi 6 Long-Range (U6-LR) units – long range access points that support the Wi-Fi 6 standard. I’ve been using the setup Ubiquit sent me about a year ago which included a Unifi Access Point nanoHD (UAP-nanoHD). I was going to start by changing that over to one of these newer units to see how it went.

First, the unboxing. I don’t bother about this too much usually when reviewing hardware, but there’s a fair bit of attention to detail here. A mounting guide for the screw holes that includes a tiny spirit level, the detailed hole explanations on the plate, and the hardware kit – an assortment of screws and brackets that come in a nice sleeved foam holder, so you don’t inevitably drop something when you would normally find these in a plastic bag to rip open.

The size difference of the Access Point nanoHD vs Access Point WiFi 6 Long-Range is substantial (and is a bit over 3x as heavy):

Comparing the specs between the two:

NanoHD:

  • Four-Stream 802.11ac Wave 2 Technology
  • Simultaneous Dual-Band Radios
  • Supports 200+ Concurrent Users
  • 5 GHz Band 4×4 Multi-User MIMO with Radio Rate of 1.733 Gbps
  • 2.4 GHz Band 2×2 MIMO with Radio Rate of 300 Mbps
  • Powered by Gigabit 802.3af PoE

U6-LR:

  • 1.3 GHz dual-core processor (now upgraded to support full-duplex 1 Gbps TCP/IP performance)
  • Four-stream high-efficiency Wi-Fi 6 technology
  • 5 GHz band 4×4 MU-MIMO and OFDMA with radio rate of 2.4 Gbps
  • 2.4 GHz band 4×4 MIMO with radio rate of 600 Mbps
  • Powered with 802.3at PoE (PoE injector not included)

Both units at the time of writing are the same price of $179US. Beyond the Wi-Fi 6 functionality on the U6-LR, the radio rates are higher and denser on it too. It’s worth noting the U6-LR has a the updated PoE requirement (also known as PoE+) and does not come with a PoE injector; if you’re already using a PoE+ switch like I am, this isn’t an issue. Otherwise, order a US$12 PoE Injector with the 802.3at standard

Swapping over the units was incredibly easy – I hadn’t mounted the NanoHD since moving, and may end up mounting this one once I’ve been using it for a bit and know I’m happy with it.

When I say it was easy; after swapping the network cable over, I logged onto the UniFi Dream Machine (UDM) web interface, went to the network devices page, and clicked ‘Adopt device’ that popped up. About a minute passed, and the device was now under control:

There was an update available, which upgraded the device from 5.43.15.12477 to 5.60.9.12980. I decided to add the second U6-LR on, but this time it would take over the Wi-Fi duties of the UDM; I adopted it into the UDM, then went into the WiFi settings for both the 2.4ghz and 5ghz networks, created a new AP Group, and ticked all but the UDM and applied (I have separate WiFi network names for the different bands due to an issue with a 2.4ghz only device that wouldn’t work when both bands were used on the same name).

Once I had done all this and let the connections settle down, the experience across each wireless AP was 92% or better. My Samsung Galaxy S21 shows a little ‘6’ next to the WiFi symbol.

I’ll take a few days living with this to see if there’s any issues that pop up, or if I notice any improvements (one sore point was a Chromecast that would dip in video quality now and then).

See the source image

It’s been going very well. No dropouts or hiccups of any sort, and I’m noticing on my mobile that I stay on 4 bars around the house rather than dropping to 3 in some areas – which makes sense now being on a long range access point.

Also I found this video also looking at the UniFi 6 LR which has some extra info and visuals:

Microsoft Teams Phones Considerations

Microsoft Mechanics just released a video about how to set up Microsoft Teams Phones which as always, is a good high level technical overview of something Microsoft is doing. Here’s the video:

Personally, I’ve been living with using Microsoft Teams as the phone system for PSTN calls for about 6 months now, after coming from Skype for Business On-premises. There are some aspects that do ‘just work’, but there’s also limitations to be aware of. For reference, I’m using it via Telstra’s TCO365 service, which may give a bit of a different experience to others not using it this way. For example, I can’t get PSTN call logs via Teams itself:

https://docs.microsoft.com/en-us/microsoftteams/teams-analytics-and-reports/pstn-usage-report

Pros:

I don’t have to worry about any gateways

With Skype for Business On-Premises, we had multiple gateways to convert the SIP calls into SfB. It’s now all happening in the cloud, I just have a range of numbers provided by the telco that turn up in Teams and can allocate them, along with the user requiring the right Micrsoft license, and the TCO365 license. There’s no specialist knowledge required to maintain any gateways, and reduces complexity of the environment. The gateways were mostly set and forget – but still needed work do to manual updates. If one had a fault, it’d be a pain to resolve.

Microsoft Teams Client

This will also appear as a con later, but everyone already uses the Microsoft Teams client for meetings – so the learning curve isn’t as bad compared to using another platform. It very much leads into the notion that beyond email, Teams is trying to be the single pain of glass for immediate interactions and communications. The client receives constant updates which can bring quality of life improvements.

Teams Admin Portal

The admin portal is generally a lot nicer to use than the old Skype for Business portal, which ran on Silverlight. It is constantly changing and being updated, and has grown in stability since I started using it 6 months ago. There’s a lot more that can be done in there around usage and reporting, and client health. There’s still plenty of improvements that can be made, but for the most part it does work.

Feature Updates

Not having to patch Skype for Business servers is great – a standard benefit of on-premises vs SaaS. The less things we have to manage for no real benefit, the better. When those updates come through, they’re regular, and bring new options to the platform. The client updates of course bring many more features too – but be weary of release dates. When something gets released in June 2021, it probably means that Microsoft are starting to roll it out then, and may take a few months to get to your tenant.

Calling Queues and Auto Attendants

The range of options around these is a lot greater in Teams – you can have a lot of scenarios covered and more complicated rulesets on how to handle calls. Members of a calling queue can also optionally have the toggle in their client if they want to be a part of it or not, which is handy to give end users the ability to jump in and out.

Cons:

Microsoft Teams Client

A double edged sword – it is nowhere near as slick and well designed as Skype for Business was for purely making phone calls. The interface is huge, becuase it’s designed to do so much; but the phone aspect still feels like an afterthought that constantly changes. Doing something simple like clicking in the field to dial a number, typing it and pressing enter does not call the number. You have to press enter twice – but not straight away, that won’t work, you have to wait for it to pop up a dialog showing it’s got the number ready to dial, then press enter again. Or, you can then go to the mouse and click call, which to me isn’t as good since I just used the keyboard to type a number in. Clicking all the digits of a phone number isn’t fun.

The Teams client is still memory hungry, has a lot of weird bugs (at one stage, the Calls icon just wouldn’t show which makes it very hard to make calls!). A whole re-write of the Teams client will come out at some stage, so hopefully that runs a lot better.

Desk Phones

This is another aspect that feels like it doesn’t get enough attention and effort. The Teams app that runs on Android will power any desk phone, and it’s not instantly quick to respond. It’s good enough, but not great. Many phones still don’t support being automatically updated via Teams, but will support a manual update. Part of the desk phone experience comes down to which third party vendor you pick, but features like being able to swap a PSTN call between desk phone and PC are still coming – these should have been there from day 1.

Unassigned Number

On Skype for Business, there was a great feature that would redirect calls of unallocated numbers in number ranges to another number – so if someone left, their calls would go to reception. This isn’t available in Teams at all, if you want to recreate the feature, you’ll have to pay license and phone company fees for every single number you’d like to do this to. A real pain.

Calling Queues and Auto Attendants

Although another positive, the internal Teams support for this is poor. If you try to look up the name of a calling queue in Teams, it won’t come up. So, if you create a Helpdesk group and expect internal staff to be able to type ‘Helpdesk’ in to find and call them, you can’t. I’m really disappointed on this one. The workaround is to fully license an account called Helpdesk, and set that to divert all it’s calls to the calling queue number.

There’s a bunch more points to consider, if you want to see a comparison on features for Skype for Business vs Teams in it’s multiple iterations of phone support (Teams Calling Plan, Teams Direct Routing, Teams Operator Connect) check out Luca Vitali’s constantly updated feature comparison table

I am looking forward to seeing how Teams Phones progresses and becomes a stronger product; in it’s current state be aware of the existing limitations and if it meets your requirements. It’s also worth seeing what’s on the roadmap for Teams and Phones to know what’s coming.

Expensive Graphics Cards and Mining Cryptocurrency

If you’ve wondered why graphics cards are so expensive – new or used, you might have wondered why. You might have also been told that it’s due to people using these graphics cards for mining, and then been annoyed that you have to pay a lot of money to get a better graphics card. Or maybe that’s all just me… but I’ve been looking into this, and playing with mining cryptocurrency; here’s what I learnt.

I bought a new PC for home with the following specifications:

The key component here is the NVIDIA RTX 3080 graphics card, and you’re lucky to get one at the time of writing for $2000AU. When NVIDIA first launched the 3080 amongst other cards in late 2020, their RRP was $1139AU. A huge price increase – so why does mining cryptocurrency affect the pricing?

To actually use your GPU to mine can be incredibly easy. Platforms such as Nicehash let you set up within a few minutes, and just run a piece of software that sorts it all out for you. The barrier to entry is very low with methods like this, and Nicehash act as a service to allow people’s GPUs to mine cryptocurrency, take a cut of the money made, and pay the people doing the work in bitcoin (and to clarify, Nicehash aren’t getting their users to mine bitcoin itself, but several other options are available – and the market constantly changes, so there’s not one particularly good ‘coin’ to mine).

There are other options such as mining Ethereum, or using HiveOS – and I’m not recommending Nicehash in particular, but it’s the one I’ve tried and makes explaining things easier.

Coming back to my above computer – if I chose to run Nicehash, they have a calculator to show how much you could make:

Ignoring electricity costs (I’ll get to that later), running the Nicehash software based on the time of writing’s Bitcoin to AUD rate, I would get paid $5.38AU of bitcoin each day.

If my RTX 3080 cost $2000AU to buy, and I left Nicehash running on it, it would take 371 days to pay for itself – if the value of Bitcoin didn’t change. At 371 days, I also still have the RTX 3080. You can probably see the problem here already, and why so many people are now mining cryptocurrency.

Historically, the value of graphics cards drops as new models come out. However, due to crypto, value has gone up. Supply can’t meet demand, and older cards have increased in value because they can pay for themselves, then start making profit with enough time and power. The NVIDIA GTX 1080 Ti which came out in 2017 at a RRP of ~$900AU. They’re still worth about that on the second hand market, because:

Buying one for $900 would take 281 days to pay for itself. That’s better value than my new 3080.

Nicehash have a list of cards, recommended general overclocking settings, and the expected performance on one particular type of coin. the MH/s is a million hashes per second measurement, which is the actual work your card needs to do to make money:

Also note that some of the newer cards are ‘Lite Hash Rate Limited’ or LHR. This is due to NVIDIA trying to make the new cards less lucrative to miners, which is what my card is. The market for newer, non-LHR cards is of course stronger with the market paying much higher amounts for these cards, being twice as efficient. Spending $3000AU on a non-LHR RTX 3080 could make more financial sense than $2000 on a LHR RTX 3080.

Of course power isn’t free – unless you have solar during the day, and enough batteries at night, so there’s running costs to consider, and the other hardware required to run the GPU. There are mining rigs that can be built fairly cheaply, running many cards at once back to a motherboard/CPU/GPUs to provide more MH/s and therefore profit:

In these rigs, devices called ‘PCIe Risers’ are used to connect the GPU back to the motherboard. The GPUs would normally need a 16x PCIe slot, but these adapters can connect to a 1x PCIe slot – so a motherboard with lots of PCIe slots is what people look for in a mining rig. Plain USB can also be used, like this Asus motherboard with 20x USB ports on the motherboard itself:


None of the above is definite – things that happen in the world affect the value of cryptocurrency – including events like China banning cryptocurrency altogether which can throw values up or down. While there’s enough money in cryptocurrency though, this will continue; unless there’s an absolutely huge market crash (which could happen just like in anything lucrative). NVIDIA could work out how to build newer cards that are worse at mining, while still being better at gaming graphics – but new NVIDIA cards aren’t due out until late 2022. AMD has a similar problem as NVIDIA, with similar profits being possible.

How to Update Your iPhone or iPad without Wi-Fi (over Cellular)

A new exploit has been patched by Apple for iOS devices – the iOS 14.8 update fixes the vulnerability that the ‘Pegusus‘ spyware uses.

Updating your iOS device is easy if you have Wi-Fi, but if you only have cellular, you’ll see a message saying ‘This update requires a Wi-Fi network connection to download’.

If you have access to another device, you can hotspot your iOS device to that and run the update. If you don’t, there’s another trick you can do to allow downloading the update over cellular:

How to update iOS over cellular

  1. Go to Settings
  2. Go to General
  3. Go to Software Update
  4. The screen should say you need to be connected to Wi-Fi and the ‘Download and Install’ option greyed o
  5. Go back to General
  6. Go to Date & Time
  7. Turn off Automatic Time
  8. Set Month three months ahead (right now that would be from October to December)
  9. Go back to General
  10. Go to Software Update
  11. Press ‘Download and Install’
  12. While that runs, Go to General
  13. Go to Date & Time
  14. Turn on Automatic Time

Applies To: iOS

It’s worth noting that I tested going a year ahead, and the update wouldn’t download, but 3 months ahead did work.

I believe this is design by Apple to avoid people downloading large amounts of data over their mobile plan, but the updates get to an age where Apple deem them critical, and it’s then better to get the update over cellular than not at all.

I hope Apple address this properly and have a toggle on the screen to just choose to download the update over cellular, with a warning about high data usage (iOS 14.8 is almost 1GB).

EA Play Chat Support

Had to share this one. I had finished setting up my new gaming PC and wanted to try a game – so thought Battlefield V would do the trick, which is ‘free’ under my Xbox Game Pass Ultimate subscription, which gives access to EA Play. Except, it doesn’t work, and doesn’t say why:

Anyway, I decided to use EA’s online chat support. Unsurprisingly, it’s not a fun experience – because online chat support rarely is. I’d already spoken to them once where their suggestion was to uninstall and reinstall the EA Desktop app, and I was coming back the next day on the same case to tell them it hadn’t worked. Read on…

It was at that stage, almost 1 and a half hours into it, that I closed the browser.
