Purchase this unit used from a reputable seller on eBay. Worked fine for 7 months, then just died.  Trying to see when it was purchased becuase TP offers a 3 year warranty on this product. Seeing these other post dosn't give me confidence in the build quality of TP.

  @nmls82 I have the SX105 V3 and it regularly dies when used with the TX401 adapters, a firmware-hardware bug between the TX401 and SX105, seems like the solution is to not use TP-Link switches with TP-Link adapters??

Hello @Vectrobe ,

Thanks for contacting our community.

 

May I know if your network topology diagram is as follows:

[ISP 10GbE]

|

| (CAT6A)

|

[BE800 Router]

|

| (10GbE via CAT6A)

|

[SX105 10GbE Switch]

├────── (CAT6A) ─── [Desktop (TX401 10GbE NIC)]

└────── (CAT6A) ─── [Server (TX401 10GbE NIC)]

 

 

If you remove the Switch or the Adapter separately, the exception will not occur, right? 

Is there any error message? Please take screenshots with the error message. Also, please tell me the model and operating system of your desktop.

  @Joseph-TP 
- incoming ISP connection is 10GbE

- this is directly attached to the BE800 router via CAT6A

- SX105 is directly attached to the BE800 10GbE via CAT6A

- desktop and servers attached directly to the SX105 via TX401 cards with CAT6A cables

 

so whole network is 10GbE with proper CAT6A, I discarded the junk fake "cat6A" cables that TP-Link bundles with the TX401 adapters as they don't physically work, instead I use ones from companies like ALOGIC and CRUXTEC

 

also what on earth are you talking about wifi for??
