Yesterday I installed an Sophos AP55C on my XG Firewall Home Edition. After about 3 hours of configuring, testing, and reconfiguring, the wifi is majorly slow. I already turned off all the network protection and scanning functions. I tried the 2.4 GHz and 5 GHz combined, and solo but still is very slow. My laptop and my phone have full coverage and the channels are free (checked with wifi analyzer). Does anyone have any more tips of how to speed up my wifi?
Are you facing the issue while using WIFI ? If so are you getting Performance issue while connected directly. ?
If so are you getting Performance issue while connected directly. ?
What are the CPU and Memory allocation to the Device in VM ?
Could you check via packet capture if there is a Latency with the connection when you ping you WIFI systems from XG appliance .
Thanks and Regards

In reply to Aditya Patel:
Yes the performance is only dramatic when using WIFI. Using cable (1Gbps) everything is as fast as aspected. Below you can see the CPU usage and the memory usage and allocation. I have not yet tested the latency from and to my wireless device. I will try that.
What encryption setting are you using for your wireless network? Make sure it is set to AES only.
I tested the wifi latency from my devices to the xg firewall and from the firewall to the devices, and it results in between 6ms - 14ms
In reply to axsom1:
Thank you for the hint. I checked twice and yes I already set it to AES only
In reply to Jeffrey Jaspers:
Check #4 in my guide here.
Any help with that?
Do you have another Access point in place , We could use that to test the comparison as well. If this does now work I would advise you to log a Support Ticket and you may direct message me along with the Link to this forum for reference ..
Unfortinutly I don't have any other wifi accesspoint that can be compared to the AP55c. I only have an old wireless N router, but i don't think we can use that for testing.
I tried to open a support ticket but I can because it is a home licensed firewall. Any advise?
Have you try to change MSS on your WAN Interface to 1410?
I have similar issue as you.
After change WAN interface's MSS to 1410, it resolved my issue.(Not LAN, not Wifi, but WAN interface!)
In reply to ShunzeLee:
Thank you for your reply, I have not tried this yet. What does the MSS setting do? I would like to understand why manually configuring the MSS setting will make the WiFi perform better. Im gonna try the setting tonight, so I'll let you know the outcome.
So I answered my own question. I anyone likes to know then read this: https://kb.cyberoam.com/default.asp?id=3098
I have no idea about MSS.
And don't understand why the MSS 1410 should be changed on WAN interface...
But it resolve my WiFi slow issue.
So I only can notice you the chance to try it.
Yesterday I tried to override the MSS setting to 1410. Further testing needs to be done, but first impression tells me it does not solve the problem.
Did you check #4 in my guide as suggested in my previous answer?
Post a picture of the output and the configuration done for AP.
In reply to sachingurung:
#4- If you have slow browsing/throughput and/or ifconfig (in advance shell) or show network interfaces (in device console) shows errors, collisions, dropped etc., try these steps, in sequence, until your problem goes away:
the average troughput of my WiFi is currently 6-10MBps
