XR500 DHCP issue
I've had this router for 4 months now and it works fine most of the time. Once in a while I'll notice that some LAN devices become unresponsive, when I look into the issue it turns out that they have...
Just wanted to add that I turned off QOS and I haven't had a disconnect since and it has been over a week. Possible issue is related to QOS with DHCP.
tekonsite What do you mean the "turn off QoS"? Do you check the "Disable QoS" from Congestion control menu?
Netduma-Fraser If disabling QoS can solve the issue, still need your team's effort to look into any iptables issue to possible block the DHCP packets.
- I can say that this is definitely related to QOS. Since I have selected "Never" under Congestion Control from "Auto Enable" I am yet to have a DHCP disconnect. I was very surprised to say that it has been stable for almost 10 days without a reboot.
tekonsite Thanks for this information. This is the Netduma feature, i need Fraser to comment on it.
Netduma-Fraser Would you help to take a look of this case of the DHCP issue?
- I have not seen it be specifically related to QoS in the past but I'll get people to test it.
I will this now see if it helps.
My disconnects are back since I enabled smart connect? I was only using 2.4gz wifi and it had been fine for weeks. only thing changed is have enabled smart connect and set up the ex7700 extender that came with the router?
- Did you get any disconnects from wired devices? Please do try that, would be interested to know the results.
No only have 1 wired pc and thats been fine
- @Delix, since you have been only using 2.4Ghz in the recent past and switched to smart connect, check to see if your wireless devices can connect to 5Ghz. Also check if they are compatible with IEEE 802.11k, 802.11r and 802.11v standards that let clients roam more seamlessly from access point (AP) to AP within the same network. That is what Smart Connect is along with a single ssid for all AP radios. The XR500 has two radios and the EX7700 has 3 radios. Hope that helps as I have the XR500 and 3 EX7700 Access points.
Def an issue with smart connect, dont get a full day without some devices coming up authentication error.
Have now turned smart connect off and 5ghz wifi. only using 2.4ghz!!
- I'm not sure if it's specifically related to Smart Connect - that's probably some devices not switching properly between 2.4/5GHz when using one SSID. There is an issue with DHCP lease I believe and NG are looking at it right now.
Def Smart connect the devices that have issues are mostly phones and we have the lastest phones Samsung S20+ so dont see why they dont work
- Delx do you notice it when using the beta at all?
