Google Nest Wifi Pro Ethernet super slow

[jramay]

Today I have setup Google Nest Wifi Pro mesh 4 pack. For internet I have AT&T 1GB Fiber connection which is setup in Passthrough mode. I was using TP Link Deco XE5300 which was giving me full bandwidth (980 Mpbs) on ethernet and(600 Mpbs) on Wifi.

Device Info
1. Firmware version 1.63.377847
2. Pack of 4 
3. AT&T Router in Passthrough mode 
4. Nothing is changed except the Wifi mesh (same wires etc)

Diagnosis
1. Running Test Mesh shows Good Connection.
2. Running Speed test on AT&T Router shows 991 Mbps download 922 Mpbs upload
2. Running Speed test on Google Home App shows 937 Mbps download 932 Mpbs upload
3. Running Speed test from browser (using different providers) using ethernet shows max download 270 Mbps
4. Running Speed test from browser (using different providers) using Wifi shows max download speed 120 Mbps. This is with having wired backhaul and sitting just 2-3 feet away from Nest router.

Solutions Tried
1. Reset AT&T passthrough
2. Toggle the IPV6 on and off
3. Restarted AT&T router and Google Nest Wifi Pro
4. Turned off Next cloud service and usage data reports
5. Tried different ethernet cables
6. Tried wired and wireless backhaul for Google Nest Wifi Pro.

Conclusion
This is unexpectedly worst quality from a company like Google and reading through all online forums and trying different solutions and I am very less hopeful that it will be fixed but still posting here so may be someone suggest something which I have tried yet. Otherwise I will definitely return Google Nest Wifi Pro and will never try it again.

Hello @jramay 

Just a few questions to help clarify your setup. First, did you set up a primary Nest WiFi Pro unit connected to your internet service via its WAN Ethernet port, then connect an unmanaged Ethernet switch to its LAN Ethernet port, and then connect each secondary Nest WiFi Pro units to that switch? Or did you connect all of the Nest WiFi Pro units directly to your AT&T router?

Second, in the Google Home app, can you check the detailed settings for each secondary Nest WiFi Pro unit to confirm they are all showing as "wired" rather than "mesh"?

Third, have you run a mesh test, and does the result for each secondary show "great" or something else?

Right now my network setup is below as I am using wireless backhaul.

Hello @jramay 

Thanks – that helps. I had keyed off the phrase "wired backhaul" in your original question. It also sounds like you had one secondary Nest WiFi Pro connected via Ethernet – was that to the unmanaged switch in your diagram, or was it to the AT&T router? If it was connected to the AT&T router, that would be bridging the inner and outer networks, which would definitely cause problems. If it was to the unmanaged switch, then that should work fine, but it should show as "wired" in the Google Home app.

In any case, can you try connecting the laptop you're using for testing directly to the LAN Ethernet port on the primary Nest WiFi Pro unit? I'm trying to break things down as much as possible to remove variables, so bypassing that switch, if only long enough to run a test, is useful.

Thanks a lot for your reply and help.
I tried wired backhaul by connecting one of the Google Nest Wifi Pro point to Unmanaged switch. It was shown as Wireless until restarted it. After the restart it showed Wired but the max download speed I got is 300 Mbps. The ethernet cable I used was connected to my Laptop and I verified that it was working perfectly alright. Once I remove the ethernet cable between Unmanaged Switch and Google Nest Wifi Pro point and restarted it which turned it back to Wireless backhaul mode it gave me 700 Mbps max download while the upload was still at 320 Mbps. However testing internet speed on Google Home App the download and upload both were at 800+ Mbps.


One more point to mention is that for wired backhaul I tried both ports of Google Nest Wifi Pro point one by one and it didn't fix/improve any speed.

[MichaelP]

Did you get a chance to try connecting your laptop directly to the primary Nest WiFi Pro unit's LAN Ethernet port?

I'm starting to wonder if that switch has loop detection, which can cause significant problems, especially when secondary Nest WiFi Pro units are connected via Ethernet. What is the make and model of that switch?

[jramay]

Please note that I am not using wired backhaul anymore all units are connected wirelessly. As I mentioned Download speeds are improved but upload is still below 500

[MichaelP]

Please try removing the switch from your system long enough to run a test directly to the LAN port on the primary Nest WiFi Pro.

Hi, @jramay , thanks for posting! I have exactly the same problem with a very similar network setup (great diagram!). Hope we get some useful answers or I will also look for a different router.

My AT&T router is a BGW320 btw.

My AT&T router is BGW210-700. Unfortunately I didn't find any help from these forums but after trying out different things at my own it appears that one of my Google Nest Wifi Pro point had ethernet cable plugged-in even if it was connected with wireless backhaul. Removing all ethernet cables between points improve the average download speed from 270 Mbps to 700 Mbps (Laptop Connected via Ethernet) but at the same time the Google Home app Test shows 900+ Mbps and AT&T router test also shows 900+ Mbps which means it is losing at least 200 Mpbs (20%) on laptop wired connections, interestingly even after removing all ethernet cables between all Google Nest Wifi Pro points the Upload speed is still max at 300 Mbps (Laptop Connected via Ethernet) while Google Home App and AT&T router shows upload speeds of 800+ Mbps .

I have Linux Home Server which monitors internet speed every 20 mins, I have all the historical test results for last 30 days and my previous TP-Link Deco AXE5300 Wi-Fi 6E Tri-Band provided average download 750 Mbps and average upload 730 Mbps throughout these 30 days.

Based on the things I have tried I think Google Nest Wifi Pro isn't good at working with any sort of switches, whether it is Managed or Unmanaged switch. It is better to get rid of Google Nest Wifi Pro and buy something which works well with other networking equipment.

I will not wait too long for any answer to come, my previous TP-Link Deco AXE5300 Wi-Fi 6E Tri-Band worked absolutely awesome for 18+ months until one of its units had issues. I will re-buy the same as it is tested for speed, range and stability, even it is cheaper if you buy from CostoCo.

I spent hours on something like this with many Google tech reps on the phone, email, etc.  Super frustrating.  Strong signal, strong mesh connectivity, diagnostics show very high incoming internet speed as do any hardwire tests, but speedtests over wifi show only moderate speeds of 60-130 Mbps.  I had one Google rep actually try and convince me that all the various speed tests were wrong because they were not Google products and I was only imagining slow speeds.  i.e. Speedtest.net said 60 Mbps but I probably was getting 300 because the router was probably fine and Speedtest.net was third-party.  What?

Bottom line is that Google Wifi has some sort of unsolvable technical issue they know about (just look on these boards, there are dozens of posts) but won't admit.  You can do every step they give you including 30 min ping tests and factory resets but nothing will help.  No matter how fast your internet is the system seems to produce wifi only at 60 Mbps on older devices and maybe 100 to 130 Mbps on newer ones.  Resetting can help but the effect won't last.

I finally threw it out and bought an inexpensive Azus ZenWifi network.  Speed immediately jumped to about 250 Mbps for all but the oldest of devices. Problem solved.

I have bought TP Link Deco X75 and will return Good Nest Wifi Pro. Didn't expect such experience and support from a company like Google.

[Mikael]

@Inwoodite . My most recent experience with Google support was very similar to yours. After more than an hour with their service guy, I still only get a fraction of the 1G AT&T signal that enters the Google router. Same song and dance questioning whether my speedtest was accurate or not (even though it did register 900 Mbps wifi signal out of the AT&T router while only giving me 300 Mbps from the Google router in the same location). I'm done and will switch to a better router brand.

@jramay I agree. I didn't expect this from a vendor like Google. I basically bought the Nest because I trusted the brand. Never again.
