AP55C on XG Firewall Home is Sloooooooow

Question

Hi all, 
 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? 
 greets, 
 Jeffrey

Ok I haven't been on the new forums much,but I work with these products a lot 
 We see this same symptom on UTM9 as well. 
 Humor me with this test to see if we can fix it and then walk it back to the setting you need 
 1. Put the radios in auto channel mode 
 2. Set 2.4ghz to 75% power 
 3. If possible set encryption to just WPA2/AES 
 4. Turn off flood control completely 
 Test 2.4ghz and 5ghz seperately using different Ssids for each 
 Do you have two wireless computer to test with in house? If so windows or mac so I can recommend a bandwidth testing tool

Ok let's walk this back a bit then then and cover the why's for everyone else. 
 
 1. Put the radios in auto channel mode -- Just smart so I would leave it. 
 2. Set 2.4ghz to 75% power -- This is important as it lets you then use the same SSID on both 5ghz and 2.4ghz we have done a ton of testing in this regard. If you set it that way then 5ghz gear will correctly select 5ghz at those distances where 5ghz is faster; and 2.4ghz when it's not. The problem with 2.4ghz right now is the specrtum is polluted by too many devices. It's not uncommon to see 2.4 ghz real world throughput to top out at 3mbps in a location where 400mbps is possible with 5ghz. When you are at 100% you will wind up on 2.4ghz far too often and at place where the human would know better an want to select 5ghz if doing it manually 
 3. If possible set encryption to just WPA2/AES - just smart that's all 
 4. Turn off flood control completely -- This is frankly broken in the current release it's stepping on valid traffic; so don't us it for the time being as it hard to spot that it's the real cause of this and many other problems

Hi Bob, 
 I followed your steps and this is what came out; 
 1. Put the radios in auto channel mode -- Just smart so I would leave it. I changed this setting from channel 13 and 116 to auto. 2. Set 2.4ghz to 75% power -- This is important as it lets you then use the same SSID on both 5ghz and 2.4ghz we have done a ton of testing in this regard. If you set it that way then 5ghz gear will correctly select 5ghz at those distances where 5ghz is faster; and 2.4ghz when it's not. The problem with 2.4ghz right now is the specrtum is polluted by too many devices. It's not uncommon to see 2.4 ghz real world throughput to top out at 3mbps in a location where 400mbps is possible with 5ghz. When you are at 100% you will wind up on 2.4ghz far too often and at place where the human would know better an want to select 5ghz if doing it manually. I enabled 2.4GHz, it was disabled at first. 3. If possible set encryption to just WPA2/AES - just smart that's all. Did not change this, already had this setting. 4. Turn off flood control completely -- This is frankly broken in the current release it's stepping on valid traffic; so don't us it for the time being as it hard to spot that it's the real cause of this and many other problems. To be honest, I could not find the option to disable it in the XG R16. 
 Im gonna use these settings as base settings and try to tweak them to how I want it to be, and experiment a little with It to see what is does an how it works. 
 Many thanks to everyone who replied.

Hi Jeffrey, 
 Yes, AP 55C works at that speed. Try to directly connect a system to XG to download a file and verify the throughput. 
 Next step, take SSH to XG and execute, wget http://speedtest.ttml.co.in/files/5M.exe . Post the output. 
 Also, try changing the speed negotiation on the hardware. Any luck with the following settings: 
 ON virtual appliance , you could not change the interface speed on XG as it does not control the hardware which is your NIC Adapter. These settings is applicable to hardware appliance. Your VM or the ethernet driver have the capability to change the interface speed . 
 How to determine the NIC speed of the ShareScan manager PC: 
 Windows XP/ 2003: 
 
 Click "Start > Settings > Control Panel". 
 Select "Network Connections". 
 Right click on the "Local Area Connection" select "Properties". 
 In the "Local Area Connection Properties" window, select the "Configure" button. 
 Select the "Advanced" tab. 
 In the scroll list of options find "Media Type" and select it. 
 The NIC speed will be displayed in the "Value" drop down menu. 
 
 Windows Vista/ Windows 7/2008: 
 
 Click "Start > Settings > Control Panel". 
 Select "Network and Sharing Center". 
 On the right panel select "Change Adapter settings" 
 Right click on the "Local area Connection" and select "Properties". 
 In the "Local Area Connection Properties" window select the "Configure" button. 
 Select the "Advanced" tab. 
 In the scroll list of options find "Speed & Duplex" or "Link Speed & Duplex" and select it. 
 The NIC speed will be displayed in the "Value" drop down menu. 
 
 Hope that helps.

As far as i know, Support found the reason and is already working on a Patch. Would expect it for next MR Release. 
 FloSupport can you track this?
