Hi all, so the problem I have today is with my Asus laptop, it has a Intel Dual band Wireless-AC 7260 wifi adapter. Not sure if that will help or not but I am going to try to provide as much information as possible. So when I am at school with my laptop one of my buildings uses channel 11 (I am using Xirrus Wifi inspector) but when I go to my other building for computer science it switches to channel 6. When I am in the first building on channel 11 I have a really slow connection, it constantly drops and hardly anything loads. When I go to the building on channel 6 everything is great. I believe that channel 6 on 2.4 gHz is a lot better but how do I set it to always use that channel even in the other building. Using Xirrus it still sees channel 6 and the signal is the same as channel 11 but it always picks channel 11. To connect to the wifi here we have to submit our mac addresses to our System Admins and then use a program (while connected to the none protected network) to auto connect us to the protected network. Is there anyways I can always use channel 6? I read a an article from a guy on an intel forum (he was a mod/support tech for intel) and he had people turn off certain settings on the wifi adapter using device management which I did and worked fairly good for a while but then I constantly kept losing connection like earlier. Speeds in that building at usually a few hundred Kbps while the building with channel 6 is 30/30 mbps

A short, practical summary and checklist to add to what described and to expand on points from and .

The wireless client cannot force an SSID to “use channel 6” — the access point (or the AP controller) decides which channel its radio uses, and clients simply associate with whatever BSSID (AP) they choose to roam to. (cisco.com)

Quick diagnosis (run from an elevated Command Prompt):

netsh wlan show networks mode=bssid
netsh wlan show interfaces
netsh wlan export profile name="SSID" folder=C:\temp key=clear
  • Use the first two commands to see each AP’s BSSID and channel and to confirm which BSSID the adapter is actually using. (learn.microsoft.com)
  • Export the profile, edit the XML to set <connectionMode>manual</connectionMode> and <autoSwitch>false</autoSwitch> (this reduces automatic roaming) then re-import with netsh wlan add profile filename="C:\temp\SSID.xml". That can force a manual association to a specific profile/BSSID for testing. (learn.microsoft.com)

Client-side mitigations that often help (but do not change AP channel):

  • In Device Manager → adapter → Advanced, set “Preferred Band” to prefer 2.4 GHz (or 5 GHz if that is better in the area), lower “Roaming Aggressiveness” to avoid frequent handoffs, and disable adapter power-savings. Update the Intel driver if available. These settings change client roaming behavior, not the AP’s channel. (intel.com)

Longer-term fixes: ask the campus/network admins to review channel planning (restrict DCA to chosen non‑overlapping channels, reduce AP TX power, or move problem APs), or push clients to 5 GHz where possible. If testing with a different USB/PCIe adapter shows different behavior, that indicates a client/driver issue rather than the AP. In managed environments, coordinate with admins — manual profiles or BSSID binding can interfere with campus auto‑onboarding or controller features. (cisco.com)

The channel is set by the WAP (wireless access point) and not your laptop. It would be nice if they had use channel 9 there as well as 1 and 5 elsewhere but you can get experts to battle over channel choices.

In this case, try another WiFi adapter. I'll give a nod to the Etekcity SI-7200ND

Some channels are defaults (6 and 11 typically) so as more people connect over those channels, the performance drops. When both are in use you should be able to select the channel your adapter will connect with for that specific SSID. You may not get better speeds, but you may be able to get more consistent connections. On my home business WiFi I use channel 9 because all of my neighbors are using channel 6 for the most part - 6 is the normal default. Running on channel 6 would be impacted by the other access points in range.
