LAPAC1200 - no gigabit connection

PoE injector: TP-Link PoE Injector Model number TL-POE150S

 

Does the injector support Gigabit speeds? According to specs found online, yes

 

Do all involved cables support Gigabit speeds? Each associated cable was tested by plugging directly into a PC's Gigabit Ethernet port, and reached gigabit speeds during tests. during AP tests, ethernet cable is plugged into the same gigabit ethernet switch as the PC. This issue is also present when connecting the AP directly to the Gigabit Router.

 

Is adapter power being used along with PoE power? No.

 

Tested with Power adapter? Yes, and results are the same.

 

AP's Setup Page -> Login -> Configuration (top) -> LAN (Left) -> Advanced -> Port settings, auto negotiation always claims a port speed of 100Mbps, with full duplex, and an operational port speed of 1000mbps.

 

if I disable auto negotiation, and set the port speed manually to 1000mbps, i still only end up with 100mbps speeds. AP is less than a year old, and has been this way since I got it.

 

Any help would be greatly appreciated.

Re: LAPAC1200 - no gigabit connection

Edit: I was mistaken. the negotiation is actually negotiating gigabit speeds, but wireless access (even on the 5Ghtz radio) is no more than 150mbps. Our internet speed is over 800mbps

What wireless settings are configured on the AP radio you are testing and what wireless client device are you using for the test?

 

Do you have separate SSIDs' for 2.4Ghz and 5Ghz signals?

Re: LAPAC1200 - no gigabit connection

Both radios were tested on a client device that has a Intel(R) Dual Band Wireless-AC 7260 adapter, capable of gigabit wireless speeds, and up-to-date drivers. Client device runs the latest build of Windows 10 64-bits with latest drivers, and all updates installed.

 

Radio 1 has 3 SSID, of which only 2 are enabled. Radio 2 has a separate SSID that only one client (the one used for testing) has login credentials for.

 

All tests were done with the client listed above being the only connected device at the time. Settings are below.


Basic Settings for Radio 1
Radio 1: Enabled
Network Mode: B/G/N-Mixed
Channel: 11-2.462GHz
Number of SSIDs: 2
No SSIDs are isolated
Max clients are 4, and 10 respectively

 

Security for Radio 1
Security mode (both): WPA2-Personal
WPA Algorithm: AES
Pre-Shared Key: Wi-Fi password is set
Key Renewal: 3600

 

Basic settings for radio 2
Radio 1: Enabled
Network Mode: A/N/C-Mixed
Channel: 165 - 5.825GHz
Number of SSIDs: 1
No SSIDs are isolated
Max clients are 0

 

Security for Radio 1
Security mode (both): WPA2-Personal
WPA Algorithm: AES
Pre-Shared Key: Wi-Fi password is set
Key Renewal: 3600

 

Rogue AP Detection disabled for all

 

Scheduler disabled for all

 

Scheduler association N/A for all

 

Connection Control disabled for all

 

Rate limit set to 0 for all

 

QoS
VLAN ID 1 for all
Priority 0 for all
WMM enabled for all

 

WDS for both radios
Spanning Tree: Disabled
WDS Root: Interface disabled
WDS Station: All interfaces disabled

Workgroup Bridge disabled for both

 

Advanced settings
Band Steering: Disabled
SSID Isolation: Disabled

 

Advanced Parameters Radio 1
Worldwide Mode (802.11d): Enabled
Channel Bandwidth: 20/40MHz
Guard Interval: Auto
CTS Protection Mode: Disbled
Beacon Interval: 100ms
DTIM Interval: 1

Re: LAPAC1200 - no gigabit connection

I should also add that the test client is also in the same room as the wireless AP in question.

Yes this is good to know.

This card is not capable of gigabit wireless speeds since it's a 2x2 with a maximum connection rate of 867mbps.

 

https://www.intel.ca/content/www/ca/en/wireless-products/dual-band-wireless-ac-7260-bluetooth-deskto...

 

Below is a quote from this Intel article:

https://blogs.intel.com/technology/2014/06/throughput-stupid/

 

The underlying assumption is that both your Wi-Fi AP (i.e. wireless router) and your client (i.e. device, like a laptop) are using the same Wi-Fi standard and configuration. For example, the maximum data rate for 802.11ac 2×2 is 867 Mbps.
The “max data rate ÷ by 2” part of the equation broadly estimates actual throughput by taking into account network overhead and environmental factors explained earlier; that number is then divided by the number of clients sharing the bandwidth to arrive at the maximum throughput. It’s important to keep in mind that the throughput formula doesn’t take into account that data rate and throughput decrease as clients move away from the AP.

The following shows how the throughput for an 802.11ac 2×2 Wi-Fi device decreases as you add clients:

      (867 Mbps ÷ 2) ÷ 1 client = ~433 Mbps per client
      (867 Mbps ÷ 2) ÷ 2 clients = ~216 Mbps per client
      (867 Mbps ÷ 2) ÷ 3 clients = ~144 Mbps per client

    (867 Mbps ÷ 2) ÷ 6 clients = ~72 Mbps per client

Now compare 802.11ac throughput with 802.11bgn 1×1 Wi-Fi commonly found in devices today:

      (150 Mbps ÷ 2) ÷ 1 client = ~75 Mbps per client
      (150 Mbps ÷ 2) ÷ 2 clients = ~38 Mbps per client
      (150 Mbps ÷ 2) ÷ 3 clients = ~25 Mbps per client

    (150 Mbps ÷ 2) ÷ 6 clients = ~13 Mbps per client

What seemed like more speed than you might need quickly shrinks to speeds that you do need, especially in a modern home setting where multiple members of a family are streaming video, playing online games, or downloading files across multiple devices. In essence: the higher the maximum data rate, the more throughput.

Re: LAPAC1200 - no gigabit connection

The following speed tests were run within the last 5 minutes. Wireless speed tests were with only one client connected to the AP. (Ethernet is directly to router)

 

Radio 1, AC Adapter, single test client, Download 86.25mbps, Upload 45.70mbps
Radio 2, AC Adapter, single test client, Download 65.05mbps, Upload 141.03mbps
Radio 1, PoE, single test client, Download 45.13mbps, Upload 34.47mbps
Radio 2, PoE, single test client, Download 66.41mbps, Upload 119.72mbps
Ethernet, Same test client (Gigabit connection verified), Download 857.39mbps, Upload 901.31mbps (Average hardwired internet speeds across the whole network)

 

At most, maybe 6 devices are attached to radio 1 (B/G/N), and mostly used for streaming music, with 1-2 devices at most streaming video. Max distance for these devices is less than 15 feet with almost full bars (1 missing bar)

Only 1 device would be attached to Radio 2, which would be the test client, located in the same room as the AP, less than 5 feet away.

 

The test results above do not quite match the information you provided. The mistake on the Intel Dual Band was mine, but the AP speeds still do not match what they should be, even for just a single client, especially for radio 2. Ethernet test shows general network congestion isn't an issue, and provides a closer estimate of actual internet speeds.


I want to use the AC radio to get the wireless speeds that are closer what is expected. the test client woud be the only device connected to that radio.

Do you disconnect the POE Ethernet and connect the AP to a non POE port for this testing?

Any devices that connect at B/G will bring all other connected devices on that radio to the same low speed.
