I am experiencing delays and reconnecting issues when connecting to RDP. Both wired and wireless.

I have purchased a new router - Linksys EA3500 - and still these issues occur.

Ping tests stated around 18ms for my connection.

My internet speeds/subscription are 120 MB down, 10 MB up. I have tested with different "Experience / Performance" settings within RDP, from low-speed broadband to high-speed broadband; all without success.

I have KIS2013 installed with default settings on both computers (wired and wireless).

What can be the issues for these delays/secs of 'hickups' during the RDP-connection?

RDP connections to where? Some box on the internet, or between boxes on your own network - wired to wireless, wireless to wireless, wired to wired?

Also what do you consider delay, 2 seconds, 5 seconds, 10, 20, 3 minutes?

RDP to some box (server) on the internet - our server 80 km away.

The server is wired to its backbone/Internet, I make a RDP-connection via my computer (wired) or notebook (wireless) from home (or elsewhere) - I use its name/alias and not the IP.

The delay is a couple of seconds (mostly 2-5 sec); screen 'freezes', reconnecting popups appears, connection is back again and I can start working again...

And this once every 2-5 minutes.

EDIT:

adjusted delay time to real circumstances

well there could always be a slight delay in resolving to its FQDN, I think that is what you meant by name/alias because those are not resolvable on the internet but a fully qualified domain name is ;) something.something.tld

so you its not really a delay in connection, but a loss of connection and reconnect

"this once every 2-5 minutes."

Are you connecting via a VPN to this server, or just the normal RDP 3389 just over the internet? Is there any firewall on the other end limiting connections to this port to only where your coming from?

You put 3389 open on the public internet and its going to get hit quite often with people attempting to log in.

If your saying it happens every few minutes I would look at logs on server side for any hints, and also would sniff the traffic from your connection. This will show you if your getting a lot of retransmission on lost packets, etc.

lagging could be upstream not fast enough to handle request, could be dns not fast enough to handle name resolution...you mention your upstream, is your upstream the upstream at home or your upstream at the office. The upstream at the office needs to be ~1Mb/s for optimal response...your down stream at home needs to be at least that. Also the dns plays quite a bit into speed, try connecting to the ip to negate dns being an issue. if it is fast connecting to the outside ip, then the issue is dns related.

it's kinda strange... when I use my cell phone with tethering (wayyy slower connection, everything is ok) on the same notebook, I have a good connection and no delay/lag.

It seems that either my modem or router is the "bad kid in town".

I just got a new router today - default settings - so that should not be the issue.

I might just check a direct cable connection from my modem to my computer (thus cancelling out the router) and see what happens...

I'll come back to this latter thing.

@ +Chris13NT, how can I prevent this? Or is this ISP-related?

Just tested it "quick and dirty" and the delay/lag is not present when connecting directly to the modem.

When I put my router in between the lag is there yet again.

There is a power/surge adapter to prevent over-voltage, but this hasn't been an issue ever since.

Might it be cable related? And that one of the UTP-cables has been damaged/is broken?

Replacing might help, but that I need to get myself some new cables....

By the way, the current cable-setup is:

ISP-entrance in my home - cable to modem, provided bij ISP - modem - cable to surge-adapter - cable to router, from there the standard 4 GBit ports of this EA3500 to computer and other periphicals + router wireless to notebook and other periphicals.

What is your dns configuration when connection directly to the modem?

start, run, cmd

ipconfig/all

What is your dns configuration when connected to the router?

start, run, cmp

ipconfig/all

change the dns on your adapter to the dns that you are getting when you are on the modem. does the same problem exist?

dns could be the problem on initial delay, or just failure to resolve - but once the connection is established and having freezes every few minutes does not seem like a dns related problem to me.

What kind of router is it? Some routers have trouble with connections over 50mbit, I had a Linksys E3000 and it couldn't cope with my 85mbit FiOS line, it would crap out every time I pegged the download.

It could be cable related but I doubt it.

I have a brand new Linksys EA3500. It should get "Transfer rates up to 300 + 450 Mbps".

The DNS I get when connect to the router is 1 IP: 192.168.1.1

When directly connected to the modem DNS server is 2 IP's: 213.48. .... and 62.179. ...

yeah those are from your ISP when connected to modem, and when connected to router your using it as your dns forwarder. This is a common setup, your router would then forward dns to those handed to your router via your ISP 213.48 and 62.179

But again if your having the issues once your connected, it seems highly unlikely that it would be dns related.

Thx. So what can it be?

unlikely sure, test it, verify it, make sure. be sure, not be somewhat sure....perhaps the router is being retarded when forwarding, it is a link in the chain....remove the link.

I thought it was initial connection....if it is not initial connection, then it is not dns related. something is happening with the traffic when it goes from router to modem.

Can you to a trace route to the IP of the RDC server? This might give a clue if you have a hop with unusually high ping.

do tracert <ip (or dns name)> in cmd

The fact that the lag only happens when the router is in the link is making me almost positive it's the router botching things.

In which setup and from where?

From my computer, connected via router, to the RDC server?

Or from the RDC server to my computer? (and also here via router or directly connected to modem?)

Off topic but in reply to Chris, my e2000 handles my 120mbit line with ease and it has a slower CPU than your e3000..

So something is up there..

It could have just been going bad, or it could have been DD-WRT's fault.

What kind of info do you need from this trace?

From which hop# there is a time out? or else?

There has been some less delays (but still annoying) with the new FW... although I had to wrestle myself through the Cisco Cloud Connect.

Still some delays.

Question remains....

EDIT:

I guess I was over-enthusiastic... delays still remain as strong as before :(

    • Microsoft further improving Windows 11 Taskbar with latest builds

      By hellowalkman · Posted

      Microsoft further improving Windows 11 Taskbar with latest builds by Sayan Sen Microsoft has released new Windows 11 builds for users flighting the Experimental channels. The new builds are 26300.8758 for Windows 11 26H2, 28120.2374 for 26H1, and 29617.1000 for future platforms. There are improvements related to the Taskbar, File Explorer and more with the new update. The full changelogs are given below: First we have the build 26300.8758: Changes and improvements gradually being rolled out [Taskbar] Taskbar customization just got easier. As we continue to make improvements to the Taskbar experience mentioned last month, we've introduced a dedicated Taskbar Size setting, making it simpler to find, understand, and personalize your ideal taskbar experience. UI showing the new Taskbar Size setting in Settings. We've also made refinements to the transitions between taskbar sizes for a smoother overall experience. [File Explorer] We've improved the reliability of thumbnail previews for cloud files in the Details pane. The pane has also been reorganized so file properties are easier to find and review at a glance. Fixed an issue where the OneDrive shortcut in File Explorer stops working when File Explorer is run in administrative mode. Fixed an issue where the confirmation dialog might display an internal Recycle Bin file name instead of the original file name when permanently deleting a file. [Sounds] Improved system sounds when using Windows in dark mode. Up next we have build 28120.2374: Changes and improvements gradually being rolled out This update includes a small set of general improvements and fixes [Mobile Device Settings] You can add and manage your mobile devices in Settings under Bluetooth & Devices > Mobile Devices. On this page, you can manage features such as using your device as a connected camera or accessing your device's files in File Explorer. [Remote Recovery Management] Added a recovery remote management plug-in to extend WinRE management capabilities for MDM providers. [Input] The emoji panel (Windows key + period (.)) now uses GIPHY as the GIF provider, delivering a smoother GIF browsing and sharing experience following the deprecation of the Tenor API. Finally we have the changelog for Windows 11 build 29617.1000: Changes and improvements gradually being rolled out [Windows Update] As announced in the Windows Update announce blog, we are now bringing a new unified update experience to reduce the number of reboots you see per month. We are starting by coordinating driver, .NET, and firmware updates to align with the monthly quality update, reducing the update experience to a single monthly restart. See the blog for more information. [Windows Magnifier] Magnifier now gives you more control over how you zoom. You can type an exact zoom percentage directly in the magnifier toolbar to land on precisely the level you need. We've also added preset step increments (5%, 10%, 25%, 50%, 100%, 150%, 200%, and 400%) to the Settings dropdown, so you can jump to common levels in a single click. Whether you need a subtle boost or a dramatic close-up, Magnifier adapts to how you want to zoom. Enter an exact percentage or jump to preset steps —5% up to 400%. Feedback: Share your thoughts in Feedback Hub (WIN + F) under Accessibility > Magnifier. [Accessibility] We're introducing screen tint, a new accessibility setting that applies a color overlay across your entire display, softening its intensity so it's easier on your eyes throughout the day. If bright, saturated screens leave you with tired or sensitive eyes by the end of a long session, screen tint can help. Screenshot showing UI for screen tint in Accessibility, with color presets and a strength slider. To get started, open Settings > Accessibility (or press WIN + U) and look for screen tint under the Vision section. From there, you can: Pick from six preset colors or choose a custom color of your own. Adjust the tint strength slider from a subtle wash to full intensity. Night light warms your display to reduce blue light that can interfere with sleep. Screen tint reduces overall screen intensity to ease eye fatigue and light sensitivity during the day. They tackle different problems and you can use both at the same time, one working on warmth and the other on intensity. Note that turning on screen tint will disable color filters, and vice versa. If you currently rely on color filters, you might need to keep screen tint turned off. Feedback: Share your thoughts in Feedback Hub (WIN + F) under Accessibility > Narrator. [Voice Access] Voice Access now supports Portuguese (Portugal), Portuguese (Brazil), and Korean (South Korea). [Audio] Continuing our work on improving Sound Settings, we've made a few more updates in this build: We've adjusted the description text for the Allow option in properties for audio devices to include the current state of the device, to improve the clarity of the text and the purpose of the button actions. "Listen to this device" is now available in properties for audio devices, so you don't need to enter Control Panel for this functionality. [Multiple Desktops] Improved explorer reliability when switching between multiple desktops. [Storage] We've updated the dialog when creating a Dev Drive to now support specifying the size in GB instead of only MB. This has also been added when changing the size of volumes under Settings > System > Storage. [Personalization] This update improves color selection accuracy when adjusting your accent color to match your wallpaper when automatic accent color selection is enabled in Personalization settings. This update improves wallpaper persistence reliability across restarts and upgrades, including better support for large-resolution wallpapers and other scenarios to prevent solid color wallpaper fallback. [Display and Graphics] Improves the reliability and persistence of applying color profiles. You can view the official blog posts here (link1, link2, link3) on Microsoft's site.
