Just installed Elementary OS 5 on a Dell Optiplex 745 and ran updates. Hardwire ethernet runs cleanly. The network manager holds a wifi connection for at most 10 minutes. On disconnecting it will only reconnect with a reboot. Wifi card is a Ralink RT2600 that works cleanly in Windows 7 and OpenSuse. lshw -class network shows: Code (Text): *-network:0 description: Wireless interface product: RT2600 802.11 MIMO vendor: Ralink corp. physical id: 0 bus info: pci@0000:04:00.0 logical name: wlp4s0 version: 00 serial: 00:0e:8e:05:b5:9b width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rt61pci driverversion=4.15.0-43-generic firmware=0.8 latency=64 link=no multicast=yes wireless=IEEE 802.11 resources: irq:16 memory:df8f8000-df8fffff *-network:1 description: Ethernet interface product: RTL-8100/8101L/8139 PCI Fast Ethernet Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 2 bus info: pci@0000:04:02.0 logical name: enp4s2 version: 10 serial: 00:e0:4c:aa:1b:d4 size: 10Mbit/s capacity: 100Mbit/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=8139too driverversion=0.9.28 duplex=half latency=64 link=no maxlatency=64 mingnt=32 multicast=yes port=MII speed=10Mbit/s resources: irq:18 ioport:dc00(size=256) memory:df8f7f00-df8f7fff memory:df900000-df91ffff Can anyone suggest a fix?

Probably not the solution you're looking for but if in your shoes I would probably replace the wifi card. Is the card built-in or in a PCIe slot? If no slots are available even a USB wifi adapter would work well.
