Google WiFi pro producing reduced speeds after Switch

[Aescheylus]

Hello!

My Google WiFi pro access points reduce speed after my switch to 90 Mbps.

I have the following setup:

Google WiFi pro to switch (currently TP link TLSG108 v5) to two additional Google WiFi pro access point. Note the one nearest the main router receives 500 Mbps but I think the 5 ghz wireless backhaul is kicking in.

tested:

1. switch directly into computer produces 500 Mbps(paid for speed).

2. switch removed; plugging Google WiFi pro directly to second WiFi pro produces 500 Mbps on the second WiFi pro or downstream unit.

Have swapped out switch with two other switches ( a netgear and the TP Link lite).

Tested the ethernet cables by connecting them from the ATT fiber modem directly to my desktop and still receive 500 Mbps.

Have even swapped out the cables with new ones that are connected directly to the switches and still no improvement.

At little lost as to what the issue could be!

Hi Aescheylus,

Thanks for reaching out to the community! I’m sorry to hear your Google WiFi Pro access point is reducing speed after switching it. Let’s fix this! I also appreciate all the efforts in trying to resolve this situation. To gather some more details, I’d like to ask the following questions:

1. Are only the Nest WiFi points past the switch affected?
2. When did the issue start?
3. Do you use a modem and router combo?
4. Which operating system phone are you using? Is it Android or iOS?

Keep me in the loop, and I can assist you with next steps.

Best regards,
Juan

Hi Juan,

1. yes

2. after implementation switch

3. ATT fiber modem with Google WiFi pro router.

4. IOS. 

please note that restarting the access points temporarily improves the speeds

Hi Aescheylus,

Thanks for following up! Let’s isolate the situation. I also appreciate the information you shared earlier. I’d appreciate it if you could check if an electromagnetic interference might cause the inconvenience.

While Wi-Fi signals are commonly affected by interference, strong magnetic and electrical fields can also disrupt Ethernet cables if they are not properly placed or shielded.

Some common items that interfere with Ethernet cables are:

• Speakers: (wired, Bluetooth, surround sound, smart speakers, TV speakers, etc.)

• Coaxial cables (for TV or internet)

• HDMI cables

• Power strips and surge protectors

• Power cords from appliances and electronics

• Electrical outlets and equipment (microwaves, refrigerators)

Please let me know if you find any of these items near your Ethernet cable.

Best regards,
Juan
