ARP REQUESTS is not receiving ARP REPLY. Most likely is either the ARP REQUEST or ARP REPLY was lost. When TCP sends ACK retransmissions because it sent a TCP packet that required a TCP response. There are not any ARP Reply to any of the ARP Requests. Most commonly, the ARP request or the ARP Reply has been dropped.
The TCP problem is because the 3-way handshake failed. The device 192.168.1.25 sends a SYN-ACK, but the capture doesn't show 192.168.1.140 sending an ACK response. Because 192.168.1.140 did not send an ACK response, the TCP handshake failed.
The 192.168.1.140 receive direction appears to be the problem. I would capture at 192.168.1.140 to check if the SYN-ACK packets and ARP Requests are received. If packets are received then I would check for signal level/quality issues from 192.168.1.140.
