I'm in the market for a mini PC unit to run XG Home on my network and I've come across a few worthy contenders (in terms of price, having quad-core CPUs, etc.) but they seem to all be running some form of Realtek NIC. One unit in particular I'm interested in (the QOTOM Q160S) appears to be running Realtek 8111E NICs.

A lot of the posts I've seen are at least a year old, if not older, so I want to know definitively; will using XG Home with Realtek NICs result in a bad time? If the choice is between dual-core Core i3 with Intel NICs vs a quad-core Celeron N1360 with Realtek NICs, which one would be the "better" choice?

the issue with the realtek NICs is they offload processing to the CPU which then becomes a bottleneck for throughput. If your internet connection is say 100/40 or smaller and your number of connected devices is quite small then the realteks will be okay otherwise you need to consider intel or broadcom. CPU should be the fastest you can get, though not the highest performance.

Ok gotcha. I'm moving soon and I'm probably going to get 150/15 min and 150/150 max, with about 15 devices (5 of which will need to stream or video call), but I do quite a lot of streaming video and video calling. Based on that, would I run into issues?

Since it's mostly me anyway I'd mostly be using XG to separate my trusted devices, IoT devices, and guest devices across VLANs, with web filtering and ATP on all networks, and IPS on the IoT and guest network.

Got it. In terms of processor, would a processor like the i3-4010Y or a Celeron 3855U be enough (both dual-core, the i3 is 4 threads though) be enough or would I need to step up to a quad-core processor?

A quad core is nice, but not essential, the dual core with hyper threading will work with capacity to spare and is not the preferred processor but if that is what you can get on your budget then that is it. The only issue really is the GUI update performance that is why I have an e3 up from a fast atom because I like to fiddle and try various issues posed in these forums.

My hardware runs on a realtek wifi adapter and i have been experiencing frequent wifi disconnection. I'm guessing its due to the realtek wifi adapter card. May i get some suggestions on which intel wifi adapter should i switch to ? Additionally, where can i get it changed?

That lastes driver you suggested (2024.0.5.101) doesn't help unfortunately. Nothing helps at this point, I feel like I've tried everything under the sun. How do I get HP to replace these Realtek adapters with Intel, that ist he solution I'm looking for.

I had the same issue with my HP ProBook G5 and the Realtek RTL8822BE. I tried different wireless card drivers. I tried reinstalling the OS and reinstalling all the driver updates from HP. Same connection problems return.

What worked for me was reinstalling Windows 10 using the Windows 10 media creation tool from Microsoft. I let Windows handle all the driver installs. I did NOT use any updates from HP; did NOT use the HP Support Assistant; did NOT download any updates from the HP website. Leting Windows handle all the drivers and the RTL8822BE is no longer disconnecting / loosing connection to wireless networks. It'has been connected for two weeks without any drops in connection.

I've opened 3 support requests for this problem. The first time they reconnected the antennae to the chip, and the two times after they replaced the chip w/ another Realtek, except this time it's the RTL8821CE. Still doesn't work, still seeing a ton of packet loss, latency, and slow to connect issues.

Looks like I'll have to go purchase a bunch of Intel chips and install them myself because HP support on this issue is non-existent. This entire experience has been a huge waste of everyones time and has been extremely frustrating. So now it's on the customers shoulders, that doesn't seem right.

Update: I replaced the Realtek w/ an Intel dual band wireless-ac 3165 and not surprsintly the problem went away. No more dropped packets, consistent wifi connection and now my users can actually work w/o fear or being disconnected. What a concept.

HP you need to address this issue. It should not be the consumers responsibility to replace faulty hardware. It's truly a shame that HP's solution is to replace the Realtek chip w/ another Realtek chip, completely tone deaf.

Did HP refuse to change Realtek to Intel module free of charge? Did you still have guarantee period? If yes. how could they refuse to? It's their responsibility. If you open the body of notebook by yourself, you lose guarantee service, no?

I also had this problem on my HP Probook 450 G5. Luckily HP offers not only the latest driver which was causing the problems, but also an older one - version 2023.66.1104.2017 Rev.A. This solved the problem for me. This driver can be downloaded from this page:

also wished to report that the older driver seems to work fine for non-Probook models, although the selfservice page for my HP Envy x360 15 did not offer the aforementioned driver -- so i just used the direct download link offered.

We found another older driver for realtek and I guess this driver produced for Asus laptops. Driver version is 2023.72.1215.2017. We are using this driver for two days. It seems working better but we are not sure that we will face another problem or not.

And we found another solution to change realtek wifi adaptor with Intel (which is using in Lenovo E490) then E480 is working with Meraki without problem. But it is expensive and time losing opration to change 220 laptop's wifi adaptor.

Last week Lenovo released new driver update for E480 and E580. We are starting to test this driver for several laptops. I will write my comments after our test. If you have same problem you can also try this update. Cisco also recommend us to try this version answering our ticket about this problem.

As the NICs are WiFi5 standard you can disable the WiFi6 features on the APs from the dashboard, that is pretty much the only thing you can do from the Meraki side for this issue. It is a simple change so might be worth it even if it is done temporarily while making other changes to the devices.

While we were doing test with Cisco Meraki engineers they offer us to disable wifi 6 and they created another SSID just for test and we did same test that you offered. First it seems it is working normally. But several hours later user informed that she has still same problem.

Thank You JimmyM. We have also addressed this problem changing E490 chip (Intel) with E480 chip (realtek) After this changing we haven't faced any problem neither E490 nor E480. It is very interesting. Because realtek worked better with E490.

We finished driver changing for realtek with older version which is 2023.72.1215.2017. Our E480's have been working with this driver for one week. It seems that this version works better than latest driver in Lenovo support page during Zoom meetings.

As I said before we found another solution about this problem. We used older driver for realtek and I guess this driver produced for Asus laptops in 2018 . Driver version is 2023.72.1215.2017. We are using this driver for two weeks. It seems that the problem has been solved with this driver. And we made some changes on windows registry to stop automatic update for this driver.

On the other side we upgraded the MR 46 AP's with firmware 28.5. We are even testing this firmware with official current Lenovo driver for realtek version 2024.0.8.122. Meraki 28.5 firmware seems better. But it is early to say it is solved completely.

Today We faced new problem with the Realtek driver 2023.72.1215.2017. Wi-fi adaptor suddenly stops the searching SSID and Laptops cannot see any SSID anywhere. we are disabling and enabling the network adaptor with admin account. I am pushing Meraki side to define this problem. Because it seems that it will not solve like this kind of temporary solution. If any of you knows facing problem with Lenovo Realtek wi-fi adaptor and MR46 then please write your problem here. I am communication with Meraki Helpdesk with the problem.

Its not just lenovo, its all 8822BE/CE drivers. We use HP and are experiencing the same with Meraki APs (not just MR46, multiple models). Driver rollback worked (2024.0.10.129 ver. on the 8822CE), but as you said we also are experiencing the WLAN autoconfig service crashing using the driver you mentioned. I'm going to try 2024.0.8.101 next to see if its old enough to eliminate the meraki bug, but new enough that it isn't crashing the WLAN autoconfig.

Reading this thread, I wish Realtek had solved this issue. I'm running a bunch of HP 250 G4's with the Realtek RTL8821CE cards and f/w load 2024.0.10.217. Connection drops after a few minutes. Tried regressing to earlier versions of their f/w but no go. My AP's are on MR 28.5. There is no single obvious cause. Windows diagnostics will blame everything it can, like can't find gateway, or there is a problem with the card (but does not always specify what the problem is). We a school and BYOD. The kids that have HP's are also dealing with this. Is this a protocol issue or something else. Getting desperate for a viable (not costly) fix.

I will have a look at that. I also have an open ticket that is exploring other options. A reboot of AP's in affected areas also relieves the issue. Not sure how long this action will hold. There is also some discussion about 802.11k. We shall see.

We are in the same exact boat. So far we have isolated the issue to the following Realtek WLAN Cards so far: RTL8822CE and RTL8822BE. Current workaround is to install the following older drivers and this works fine for connectivity but not sure if it has other side affects. If we install the latest driver from HP, Windows Update the problem comes back.
