WIFI problem - ping latency is high - Realtek RTL8822BE 802.11AC PCIE Adapter on Zbook G5

[jurjak]

Hi everyone. 

I have problem with my WIFI card. I thought, that problem is in drivers, but after few minutes I know that doesn't. During work ping latency will be higher - from 50 - 2000ms. Normally and after restart windows it is OK - from 1 to 6ms - problem will start after reboot from few seconds (about only first ten pings to gateway is OK) to few minutes.

Then problem repeats.

Please don't tell me how to update drivers. I tryed Microsoft original, from HP Support site, and from Realtek site. Now I have the latest version 2023.58.731.2017

A also tryed diagnostic startup only.

Any ideas?

Thanks.

Hi, did you ever find a fix for this? I'm currently having the same issue with the same lan card.

I'm having this same issue now as well (HP Omen ce0xx - 1JE70AV). I've tried uninstalling and reinstalling the drivers from both HP and Microsoft's website. The PING is stable most of the time, but then spikes up to about ~2700ms (or outright times out) and then recovers a second later. I have had this laptop since May and haven't had any issues with it thus far. I plan to purchase a different wireless card to see if that solves the issue. Ethernet remains stable at this time.

Hi there,

I have the same problem with a ProBook 430 G5. There's also a RTL8822BE built-in. It seems to be a known problem not only in HP devices, but what's the solution? Swap card to another manufacturer?? 😉

Have you ever tried to contact the HP Support? Probably they only would send a replacement card... 😕

Greetings.

I conducted a great deal of additional troubleshooting on this issue. A different network card had no effect. I systematically tested every possible component (reinstalled the OS, tested on different wifi networks, tried a USB wifi adapter, etc.). Throughout all of these tests nothing changed. Then I remembered that I installed an HP firmware update that was released on July 24, 2018. I went through and checked through every setting and then I found it...Control Panel --> Hardware and Sound --> Power Options --> Edit Plan Settings --> Change Advanced Power Settings --> Wireless Adapter Settings --> Power Savings Mode --> Maximum Power Savings. Well! That'd explain why the wifi is on the fritz! I flipped that setting to "Maximum Performance" and the problem was solved...mostly.

Connectivity on the 2.4GHz band was perfect, but on the 5GHz there was severe lag spikes every 10 PINGs or so. That led me to suspect wireless interference. As such, I downloaded  WifiInfoView, a tool made by an organization called NirSoft that allows you to see all wireless signals in range of your wifi adapter. As it turns out, my neighbor had a wireless access point broadcasting on the same 5GHz channel as my network's AP. Swapped the channel on my AP and the problem is now resolved. If you are still struggling with this issue, then feel free to post back here. Let me know what you've tried and I'll try to give you some things to test.

Edit: Interesting note - When the HP Omen is on battery power the wireless adapter behaves as if it were in power savings mode. There is no means of forcing the adapter to behave as it would with a DC power supply. I speculate that this may be due to insufficient battery voltage to adequately power all of the hardware in the laptop at maximum performance. As such, 0/10 would not advise gaming on the HP Omen over wifi while on battery power. Granted you'd  drain the entire battery within 90 minutes regardless...but still, you really can't play online games with this kind of wireless performance while on battery power.

Hi Omega414, Thanks for your post. You have helped me solve this issue!

My laptop is HP Pavillion X360 using RealtekRTL8822BE, and I have home router which broadcasts 2.4 Ghz and 5 Ghz WiFi.

The PING latency is very high (1000ms - 3000ms), so i updated the driver:

Device Manager > Network adapters > Right click Realtek RTL8822BE > Update Driver

I also applied your suggestion for the Maximum Performance under battery mode.

This reduces the PING latency, but it still has request timeout and intermittent high latency.

The laptop can only detect WiFi 2.4 Ghz, but it cannot detect WiFi 5 Ghz. Currently, it connects to WiFi 2.4 Ghz.

Since 2.4 Ghz is a common frequency which is also used by household appliances. I assume the signal is not strong and might conflict with my neighbour WiFi.

So, I use your suggestion to check the WiFi surroundings using wifiiinfoview and then i can see the laptop can detect my neighbour 5 Ghz WiFi which are using channel 36 and channel 44. 

To avoid conflict with my neighbour WiFi channels, i change the router 5 Ghz channel to use channel 40. Now, my laptop can detect and connect to 5 Ghz WiFi with impressive speed up to 192 Mbps Download and 125 Mbps Upload!

Further information from this article shows that 5 Ghz has different categories, and it seems Realtek 8822BE can only detect UNII-1 category (802.11a channel 36 until channel 48).

Hope this will help others who have similar issue.

If youre still stuck with the issue... something weird happend to me. I have the Realtek 8822BE as im using the motherboard z370-E and I've tried everything but the issue was actually very simple on my part. So if you are pulling your hair out and dont know what to do and tried everything... here is how I solved it.

Firefox stole my internett simple put. Thing is that a quick look on task manager shows that it only uses 0,1MBps which is normal to show activity but a deeper look on Performance shows some weird jumps... which explains the ping issue but not where it came from. So my firefox somehow got triggered by different pages and started using all my bandwith while browsing which is really weird. To solve this I have to quit Firefox but also make sure that its gone from task manager and my ping gets stable. Its insane how I missed something so simple. So if you are stuck, this might be a thing for you as well.

Thank you a lot, i think you solved my problem with this answer. It looks like this is this setting on battery mode which affected the pci card.

En francais pour ceux qui chercheront une solution : concrètement, sur un HP 2018 avec Carte PCI Realtek RTL8822BE, j'avais comme étrange problème que si internet/le wifi fonctionnait bien les premières minutes, après quelques minutes, la connection se perdait et internet ne fonctionnait plus. Il semble que ce soit un paramètre lié à l'économie d'énergie pour usage hors secteur qui en soit la cause. Pour corriger : options d'alimentation, options avancées, et changez le mode sur PCI Card.

I have tried every "fix" out there.  My new HP, using Realtek RTL 8822BE 802.11ac still keeps dropping off internet.  My internet says I am "connected", yet the wireless adapter does not find the "default gateway".  It is beyond frustrating. 

I checked the channels. . .none conflicting with my neighbors.  My laptop has dropped internet at my house, my son's and even when connected to a hotspot on my phone. (None of those have conflicting channels.)

Do not know where to do from here.

I'm having the same issue on any of the new HP G6 laptops that come with these wireless cards. I've updated EVERY driver including the BIOS but two of the machines are still experiencing the issue. The other few I haven't heard back on but they're more frequently connected via ethernet.

Same symptoms, WiFi says connected for a few minutes, during that time cannot ping gateway. Then it'll drop and become a pain in the ass to reconnect.
