Router
Changed out the old Linksys E2500 router today for an upgraded Linksys EA6350. Two problems are addressed. First the E2500 has the lowest lan-to-wan throughput of any Linksys router, per tomshardware.com. The EA6350 is much better. Second, out of all the Linksys routers the E2500 is one of only a few that are susceptible to the new vpnfilter malware, per https://www.symantec.com/blogs/threat-intelligence/vpnfilter-iot-malware. The E2500 has blocked some web sites even when using the I.P. address which is a good hint that it has the malware.
