Hi, I just purchased this router yesterday, so I can upgrade my home network. So far the Wi-Fi seems to work fine. However, there's a limitation over LAN with a specific device. 
 

I'm currently working from home and have to be hardwired. I'm using a supplied 25ft CAT5e cable to connect the router to an HP universal dock G2. 
 

My internet service includes speeds of 150 Mbps download and 10 Mbps upload. My old router (Belkin n150) that the TP-Link AX1500 replaced used to provide about 70-80 Mbps (multi-thread test through testmy.net) to that setup. Now, I'm only seeing 40 Mbps on multi-thread tests and around 15 Mbps on single thread tests. 
 

I tried troubleshooting last night after my shift was over and could not figure out why the speed is limited. I connected my old Toshiba laptop to the same CAT5e Ethernet cable and was getting on average about 90 Mbps download speed (the laptop has a built-in LAN port with a max speed of 100 Mbps. So, the speed I was getting on the laptop was pretty good, considering the LAN port is limiting the connection to 100 Mbps. 
 

The TP-Link router seems to have an issue with the HP Universal Dock G2 for some reason. I believe it was a Gogabit switch, so I don't know what the problem is. 
 

Any suggestions?
