Can I use devolo products in power strips with surge protection?

The majority of power strips with surge protection available in stores will cause impairment of the devolo network‘s performance and thus can be recommended only to a limited extend. An exception is models designed specifically for operation in combination with devolo adapters.These are available, for example, from APC in its PL8VT3 and PL5B models.

How do devolo devices behave in the event of power surges (such as lightning strikes)?

devolo products are protected from overvoltages and power surges in the mains supply network according to national and EU-wide regulations and standards. Compliance with these regulations is reviewed and confirmed by independent accredited laboratories. devolo products are always safe, i.e. the devices never pose a danger, even in the event of a power surge.In rare cases, local power surges (e.g. nearby lightning strike) may exceed the defined voltage level. In these cases, the built-in surge protection that is a feature of devolo products is activated to avoid further damage. The device usually becomes inoperable in the process.Connected devices (via network cable or the integrated power outlet) are not protected by this feature. Here, we recommend connecting a power strip with surge protection to the product‘s power outlet.

What is the advantage of range+ technology?

The devolo range+ technology optimises the data transmission of the products in your home. Every mains supply is different. Therefore, it is important that the adapters adjust to the conditions at your home.From our more than ten years‘ experience, we have developed a technology that not only makes additional use of the earth wire for data transmission, but also brings the data signal to the power line in optimal form. The transmission and reception technology have also been improved to make reception technology as efficient as possible.

What are the prerequisites for using dLAN®? Where are the limits?

dLAN® works throughout the entire mains supply network of the house or apartment, regardless of whether the building is old or new. Of course, the network has to be on the same wiring, and the wire length must not exceed 300 meters. However, different phases are not a problem. Power meters attenuate the signal strongly, but do not necessarily block it.

Why don‘t devolo adapters need phase coupling?

Due to the high-frequency cross talk, the data signals are distributed to all phases automatically. The only requirement for this is that the phases run parallel. This high-frequency cross talk is a type of attenuation and can cause power loss.

Can I use devolo products even if I have different electrical circuits in my house?

Yes, devolo products also work if you have multiple circuits (phases) in the house. You do not have to modify the mains supply, such as by installing a phase coupler.

Can my neighbours eavesdrop on my data? After all, they are connected to the same electrical wiring!

Whether your neighbours receive the data signal of your devolo network depends on your home‘s mains supply network. Power meters and long cables can drastically diminish the signal. To be on the safe side, we recommend encrypting your network using the encryption button on the adapters or the devolo Cockpit software.

Can I also use devolo products in power strips?

In a few cases, power strips - particularly those with integrated switch and surge protection - can impair performance. To attain optimal connections, we recommend using devolo products with integrated (pass-thru) electrical socket and plugging the power strip into the devolo adapter.

Do devolo adapters work together with HomePlug adapters from different manufacturers?

All adapters that are certified to the HomePlug standard are compatible and work together. To connect devolo adapters to HomePlug adapters from different manufacturers to form a common network, assign all of the devices the same password.

Configure the devolo devices as usual:

Start dLAN® Cockpit.
Enter the security IDs of all dLAN® adapters.
Assign the shared network password.

Now, assign the other HomePlug devices the same password as the dLAN® devices according to the manufacturer‘s instructions.

Are dLAN adapters of different speed classes (200, 500, 650, 1200) compatible?

Yes, dLAN products of different speed classes are fully compatible with each other.

The only exception here is old devices with a speed of 14 and 85 Mbps. Unfortunately, these are not compatible with current products.

For technical reasons, devices from the devolo Magic series are not compatible with dLAN devices.

In a mixed network, each adapter connects to every other adapter at the highest possible speed. It does so independently of the other adapters in the network. In a network consisting of a 500 Mbps adapter and two 1200 Mbps adapters, for example, the 500 Mbps adapter will connect to the 1200 Mbps adapters at a speed of 500 Mbps. At the same time, the 1200 Mbps adapters connect to each other at the full 1200 Mbps.

Why is the product equipped with Fast Ethernet ports?

The product‘s focus is on Wi-Fi speed; in addition, the product is designed for high energy efficiency. The limitation to Fast Ethernet made it possible to install particularly energy-saving components. This is reflected in the product‘s low power consumption, both during operation and in standby mode. The transfer rate the product can attain is sufficient for most applications, such as Internet extension, HD video streaming and data backup. For more advanced applications, we also offer products with Gigabit Ethernet ports.

With which operating systems are devolo adapters compatible?

devolo adapters work independently of operating systems and are compatible with most network devices that transmit data by IP signal. They then act like a long network cable. Only the optional additional software depends on the operating system. We offer devolo software for all current operating systems such as Microsoft Windows ®, Mac OS, Linux, Android and iOS. Details can be found in the description of the respective product.

This is a hands-on tutorial of some of the most commonly-used DevTools features relatedto inspecting network activity for a page.

See Network Reference if you want to browse features instead.

[!VIDEO embed/e1gAyQuIFQo] -->

When to use the Network panel

In general, use the Network panel when you need to make sure that resources are being downloaded or uploaded as expected. The most common use cases for the Network panel are:

Making sure that resources are actually being uploaded or downloaded at all.
Inspecting the properties of an individual resource, such as the HTTP headers, content, size, and so on.

If you are looking for ways to improve page load performance, do not start with the Network tool. There are many types of load performance issues that are not related to network activity. Start with the Audits panel because it gives you targeted suggestions on how to improve your page. Navigate to Optimize Website Speed.

Open the Network panel

To get the most out of this tutorial, open up the demo and try out the features on the demo page.

Open the Get Started Demo.
Open DevTools by pressing Control+Shift+J (Windows, Linux) orCommand+Option+J (macOS). The Console tool opens.
You may prefer to dock DevTools to the bottom of your window.
Select the Network tab. The Network panel opens.

Right now the Network panel is empty. DevTools only logs network activity after you open it and no network activity has occurred since you opened DevTools.

Log network activity

To view the network activity that a page causes:

Reload the page. The Network panel logs all network activity in the Network Log.
Each row of the Network Log represents a resource. By default the resources are listed chronologically. The top resource is usually the main HTML document. The bottom resource is whatever was requested last.
Each column represents information about a resource. In the previous figure the default columns are displayed.
- Status. The HTTP status code for response.
- Type. The resource type.
- Initiator. The cause of the resource request. Selecting a link in the Initiator column takes you to the source code that caused the request.
- Time. The duration of the request.
- Waterfall. A graphical representation of the different stages of the request. Hover over a Waterfall to see a breakdown.
Note
The graph above the Network Log is called the Overview. You will not use the Overview graph in this tutorial, so you may hide it. See Hide the Overview pane.
After you open DevTools, it records network activity in the Network Log.
To demonstrate this, first look at the bottom of the Network Log and make a mental note of the last activity.
Now, select the Get Data button in the demo.
Look at the bottom of the Network Log again. You should see a new resource called getstarted.json. Selecting the Get Data button caused the page to request this file.

Show more information

The columns of the Network Log are configurable. You may hide columns that you are not using.
There are also many columns that are hidden by default which you may find useful.

Hover on the header of the Network Log table, open the contextual menu (right-click), and choose Domain. The domain of each resource is now shown.
Tip
See the full URL of a resource by hovering over the cell in the Name column.

Simulate a slower network connection

The network connection of the computer that you use to build sites is probably faster than the network connections of the mobile devices of your users. By throttling the page, you get a better idea of how long a page takes to load on a mobile device.

Choose the Throttling dropdown, which is set to Online by default.
Choose Slow 3G.
Long-press Reload () and then choose Empty Cache And Hard Reload.
On repeat visits, the browser usually serves some files from the cache, which speeds up the page load. Empty Cache And Hard Reload forces the browser to go the network for all resources. This is helpful when you want to see how a first-time visitor experiences a page load.
Note
The Empty Cache And Hard Reload workflow is only available when DevTools is open.

Capture screenshots

Screenshots let you see how a page looked over time while it was loading.

Choose () and turn on the Capture screenshots checkbox.
Refresh the page again using the Empty Cache And Hard Reload workflow. Navigate to Simulate a slower connection if you need a reminder on how to do this.
The Screenshots pane provides thumbnails of how the page looked at various points during the loading process.
Choose the first thumbnail. DevTools shows you what network activity was occurring at that moment in time.
Choose () again and turn off the Capture screenshots checkbox to close the Screenshots pane.
Refresh the page again.

Inspect the details of the resource

Choose a resource to learn more information about it. Try it now:

Choose getstarted.html. The Headers tab is shown. Use this tab to inspect HTTP headers.
Choose the Preview tab. A basic rendering of the HTML is shown.
The tab is helpful when an API returns an error code in HTML. You may find it easier to read the rendered HTML than the HTML source code, or when you inspect images.
Choose the Response tab. The HTML source code is shown.
Tip
When a file is minified, choose the Format () button at the bottom of the Response tab to re-format the contents of the file for readability.
Choose the Timing tab. A breakdown of the network activity for the resource is displayed.
Choose Close () to view the Network Log again.

Search network headers and responses

Devolo Network & Wireless Cards Drivers

Use the Search pane when you need to search the HTTP headers and responses of all resources for a certain string or regular expression.

For example, suppose you want to verify that your resources are using reasonable cache policies.

Choose Search (). The Search pane opens to the left of the Network log.
Type Cache-Control and select Enter. The Search pane lists all instances of Cache-Control that it finds in resource headers or content.
Choose a result to view the resource in which the result was found. If you are looking at the details of the resource, select a result to go directly to it. For example, if the query was found in a header, the Headers tab opens. If the query was found in content, the Response tab opens.
Close the Search pane and the Headers tab.

Filter resources

DevTools provides numerous workflows for filtering out resources that are not relevant to the task at hand.

The Filters toolbar should be turned on by default. If not:

Choose Filter () to show it.

Filter by string, regular expression, or property

The Filter text box supports many different types of filtering.

Type png into the Filter text box. Only the files that contain the text png are shown. In this case the only files that match the filter are the PNG images.
Type /.*.[cj]s+$/. DevTools filters out any resource with a filename that does not end with a j or a c followed by 1 or more s characters.
Type -main.css. DevTools filters out main.css. If any other file matched the pattern they would also be filtered out.
Type domain:cdn.glitch.com into the Filter text box. DevTools filters out any resource with a URL that does not match this domain.
See Filter requests by properties for the full list of filterable properties.
Clear the Filter text box of any text.

Devolo Network & Wireless Cards Drivers

Filter by resource type

To focus in on a certain type of file, such as stylesheets:

Choose CSS. All other file types are filtered out.
To also see scripts, hold Control (Windows, Linux) or Command (macOS) and then choose JS.
Choose All to remove the filters and see all resources again.

See Filter requests for other filtering workflows.

Block requests

How does a page look and behave when some of the page resources are not available? Does it fail completely, or is it still somewhat functional? Block requests to find out:

Select Control+Shift+P (Windows, Linux) or Command+Shift+P (macOS) to open the Command Menu.
Type block, choose Show Request Blocking, and select Enter.
Choose Add Pattern ().
Type main.css.
Choose Add.
Reload the page. As expected, the styling of the page is slightly messed up because the main stylesheet has been blocked.
Note
The main.css row in the Network Log. The red text means that the resource was blocked.
Deselect the Enable request blocking checkbox.
