CISCO RV345P - Adding WIFI

[MCSD]

    I have a Cisco RV345P Router now and I am looking to add WIFI to it. This would be to allow users on WIFI to work as if they were wired "ie: use Wired printers, surf the web".  I have listed out below what I have done so far and what issues I am having. 

        I am using a Linksys WIFI router EA7450. I put it in Bridge and turned off dhcp mode, plugged in a cable to port one on the Linksys, and then plugged the other end into port number 7 on the Cisco RV345.

Users were able to connect and get an IP address in the same subnet, and could see the wired printers and print, even the internet worked.

Then we started having issues with it:

The people on the wired connections started to have time-out issues when using rdp connections.

Users using the VPN connection got connection attempting to reconnect errors every 3-4 minutes. It would reconnect in about 10 seconds but would keep repeating the cycle.

Also, the WIFI internet would sometimes go out for a while and come back later.

  Once we unplugged the Linksys the issues above for wired users would stop and start working fine again.

Any ideas on what to look at or try?

Thanks

Hello,

tough one. My guess is that the wireless clients connected to the EA7450 starve the bandwidth of the RV345 (and its connected clients)...

The RV345 does not have too many settings to control or police the traffic on LAN ports. The Linksys by default prioritizes wireless traffic, possibly the RV345 inherits these markings. Try and turn that setting off on the Linksys (check the link below, I am not sure if your GUI looks exactly the same), but the setting is under the 'Applications & Gaming' tab, it is visible as 'WMM Support' and the 'Enabled' is on by default. Disable that feature and check if that makes a difference.

Thank you for the quick replies. I have looked in the logs on the Cisco and there are no errors listed when I have the issue going on.
I did go out and buy a new WIFI router to see if maybe the Linksys one was bad. I got a Netgear AC1900 Nighthawk, I configured it and hooked it up "I plugged port one of the Netgear into Port 7 of the Cisco and it got me connected via WIFI, but no internet at all. I did check on the Netgear and Cisco and the Qos is disabled. I was not having any issues with lag or VPN or RDP drops.
I then thought to try and connect the ISP router directly into the Netgear WAN port, and when I did I had internet and was still able to print to wired printers “so I now have two cables connected – one from Cisco to Netgear and one from ISP router to Netgear”. I watched the RDP and VPN connections for about 30mins and all seemed fine. I checked back about an hour later and VPN connections started to drop every 3-4 minutes again, as well as the rdp connections. I know the double cable is not needed and the first cable should provide both but when it was not I tried this option to check and validate. I am not sure what am I missing here?
