I’m connected to AT&T 1 Gbps fiber. I was provided with modem ARRIS NVG589. It is also a router but its features are quite limited. Moreover, I don’t want to build my home network where the core device does not belong to me.

And I decided to turn it into the dumb modem that passes everything to the router that I own and can control. In this case, I can easily switch from one provider to another without needing to reconfigure the core device. And it turns out it is quite easy. I assume the modem only handles internet traffic and does not have telephony or TV.

Firstly you need to find the MAC address for the WAN port of

I did a trip in rain and would like to write a few words about the experience.

Wipers on auto

Wipers on auto just suck. They work completely unreliable. Sometimes they work when the glass is clear. Sometimes I barely can see thru and but they decided that everything was fine and I had to activate them manually. In one place I saw that they barely work but as soon as I stopped, they started to work quite fast even though there is not much water on the windshield when the car stopped.

So far auto wiper is the biggest disappointment in my new Tesla. I was driving in changing conditions and I had to constantly adjust the speed of


As I wrote before, I had the plan to replace my main router (TP-Link Archer C7) with a Cudy X6 router and place an Archer C7 instead of my 10-year-old router. But before I was able to execute my plan, I bought Tesla Model Y.

But then I found out that Tesla is not able to get a stable connection to any of my routers. And Wall Connector has a similar issue. As a result, I had to put Archer C7 close to my computer, so Tesla and Wall Connector can connect.

So I had to buy yet another router. Initially, I thought I will buy another Cudy X6 router, but as I wrote here, it has


Today I drove 125 miles (201 km) to the airport and back. Initially, when I entered this trip into the navigation system, it showed that I will need to charge my Model Y Long Range on way back. It told me that I’m missing around 2-3% of the charge. It was frustrating because according to Tesla, my car has a range of 330 miles. I know that 330 miles is a range in close to ideal conditions but I was absolutely sure it will be enough to drive 250 miles.

Then I searched the internet and according to a few articles typical range is ¾ of what Tesla is officially stating. And ¾ from 330 miles is 247 miles,

Some of you know that the router inside is actually a small computer. And like any computer, it has an operating system. Some vendors wrote their OS and some adopt existing ones. These days, most of them use the existing OS because write own OS is very hard and costs a lot of money. With existing OS vendors just need to write a network driver and some kind of user interface.

And even writing a network driver is not an easy task. You need developers who are experts in that field and thousands and thousands of hours to make sure that it is stable. As you can imagine, it cost a lot of money and the vendor cannot work for

Here is an update on Cudy X6 after close to two months of use.

After I made Cudy X6 my main router, I had 2 cases where I shortly lost connectivity for about 10 seconds. First time I was quite busy and then forgot it, but the second one happened when I had time to research and I found this in logs:

NETDEV WATCHDOG: eth0 (mtk_soc_eth): transmit queue 0 timed out

This issue was happening around once per 10 days. After some

Just as an update after my first technician visit. Just a reminder initially I had the following problems:

  1. I cannot unplug the charger when it is finished charging. I need to unlock the charging port from Tesla app first.
  2. I cannot open the trunk by pressing a button on the back of my trunk to open even though I have my phone with me.

And as turns out, it looks like both of these issues are correct behavior. Let me explain them one by one

Charger issue

It turns out that by design, you cannot unlock the charger when your car is locked. You will have to unlock your car to unplug it, or you have to unlock

I have new Tesla Model Y for about 1 week and I would like to summarize what new buyers can expect to make sure they will not be disappointed. I will split everything into the following categories: good, bad, and in-between.


Most of the functions of your new car are controlled by a computer and a lot of functions are quite ambitious. And even Tesla is making EVs for more than a decade it is nothing from a software point of view. So be prepared to deal with glitches and bugs in software. Just as an example, I would like to connect my car to the Wi-Fi network. It couldn’t see my Wi-Fi network, so I decided to add

Recently I became a happy new Tesla owner. If you are thinking or planning to buy Tesla in near future I think it will be helpful for your to read this post. There are many gotchas on the way and I would like to highlight the most important ones.

As probably most of you already know, you have to order Tesla online. And the price is the same for everyone. There could be some difference in price between different states or countries due to local regulations, but the core price is the same. It is not possible to reduce the price as you can do with most other car vendors. The price is fixed and you can buy it or
