Thanks everyone for your responses! The environment is a high-density, high-utilization co-working location. There can be over 300 people in the space. I currently have a mix of MR32, 33, and 42s in the space. Running everything on auto except the channel width which I had set to 40. I've had both connectivity issues (people getting booted off the AP) and speed issues. I don't have DFS turned on and am not using any DFS frequencies.

Hi! I have an environment with MR42s and it has been recommended to change the default 5GHz channel width from 40 to 20. Everything I can find seems to indicate that 40MHz or greater is the way to go for 5GHz. I see almost nothing touting the benefits of a 20MHz channel width. Anyone have any insight on this? Thanks! Doug

HI! Very recently I began seeing a lot of Source IP and/or VLAN mismatch entries related to when devices such as computers and VoIP phones are plugged into the LAN. When that happens, the device cannot connect to the LAN and cannot access the Internet. We have a MX-100 and 4 HP layer-3 switches, and MR-16 APs. The MX-100 is configured with 3 VLANS 20, 26, 121. Two HP switches are daisy-chained to port 3 on the MX, which is set to VLAN 20. The other two HP switches are daisy-chained to port 7 on the MX, which is set to VLAN 26. The third VLAN is currently inactive. There is not a physical connection between the two sets of switches and I don't allow any other VLAN traffic on those ports. Network jacks are duplex jacks...one is for VLAN 20 and the other for VLAN 26. This issue just started out of the blue even though this configuration has been in place for months. Also the LAN performance has become terrible. Any thoughts?

OK. Thanks for the response...that is what I thought. In order to guarantee 10Mbps on the one VLAN, I will need to throttle bandwidth on the other VLANs.

I've set up a group policy on the MX100 for 10Mbps up and down bandwidth, assigned it to a VLAN and assigned the VLAN to a port on the MX. By setting up bandwidth limits on the VLAN, does that have an impact on the other VLANs? In other words, if the total Internet pipe is 200Mbps and I create a group policy for 10Mbps up and down bandwidth, does that restrict the rest of the network to 190Mbps?

No bandwidth shaping configured. The firmware for the security appliance, switches and AP are old...3 to 5 versions old. Didn't necessiarily see much about DNS though, but will get the firmware upgrades a shot.

On one of our networks, we have wireless client devices that when on the BIG SSID have no problems connecting to the Internet. However wireless devices on the SMALL or MEDIUM SSIDs are experiencing extremely slow access or no access to the Internet. I tested pinging 8.8.8.8 and google.com from different wireless devices. When the wireless client is connect to BIG, both pings resolve quickly and respond with < 5MS response. When same devices are connected to SMALL or MEDIUM, then the 8.8.8.8 pings resolve quickly. But pings to google.com either time out or respond in 50 - 90 MS. BIG and SMALL SSIDs utilize Meraki DHCP. The MEDIUM SSID utilizes local NAT. Because of the performance issues for name resolution of "google.com", it seems like a weird DNS issue, but if DNS was the root cause, it seems like it would affect all SSIDs, but its only affecting two of three SSIDs. Any thoughts and/or suggestions?

Thanks! I've seen the coverage patterns for the MR18s and 32s, so thought this would be the case, but wanted to see what others have experienced. Also in doing some RF surveys, depending on the materials making up the wall, the backside RF seems very weak compared to the front side. So didn't know if I would get more RF bank for the buck mounting the APs differently.

Have a client with a few locations, each with over 15K sq ft and with 20' tall ceilings. I've been installing the MR-18s and MR-32s on walls, about 12' up from the floor, using the included wall plate.
Should I have been installing face down from the ceiling joists? Would that give me better coverage vs wall mounted?
What are your thoughts on this?

Hi BHC_RESORTS, How do you enable adaptive 802.11r? Thanks! ~Doug

Hi Community!! Have a location with 3 SSIDs using Meraki DHCP. I've set "Clients Blocked from using LAN" to "Yes", so WLAN users cannot get to the LAN. So WLAN users access to LAN-based printers is disabled. So the client wants to have only their employees to have access to printers from the WLAN. I can easily do that by changing the "Clients Blocked from using LAN" from Yes to No. But the three SSIDs are used by both the users clients and employees. I have a full Meraki stack. Is there anyway to set this up so that only certain people have access to the LAN? I don't want to create a separate "employee" SSID. Thanks! ~Doug

I used the same SSIDs across all 4 locations...works great! Single splash page is not an issue.

I have a full Meraki stack with a MX-100 and three MS-225s. I want to assign a static IP to the each of the switches and for some reason, it keeps defaulting back to a DHCP address in VLAN 1. Any thoughts? ~Doug

Thanks everyone for their responses. I will give the Minimum BitRate a shot as soon as I get a maintenance window from the client. ~Doug

Thanks for the response! I've not thought about this, so this looks promising. Minimum Bit Rate doesn't affect 802.11n/ac. Any thoughts on stickiness for those?

Hi there! I support a couple of large shared space co-working locations (think of giant coffee shops on steroids). These locations can host over 200 people and the space is a combination of open floorplan, very large meeting rooms (host over 100 people) and 10 - 15 small to medium meeting rooms / offices (host 2 to 10 people). The space is about 5K sq ft and is located in a very RF busy environment. We currently have a full Meraki stack (MX80, MS320, and 6 MR32 AP) and with band-steering, push as many devices to 5GHz. However, I've had to really throttle the AP transmit power to help with client/AP stickiness issues as people roam about the space. Before making changes, clients would connect to an AP on one side of the space and stick to that AP even though they roamed to the other side of the space. Their device had just enough signal strength to the far-away AP that they would flip to a much closer AP. Now after the changes, the signal strength for anything but the closest AP is very low, which has helped most clients roam from one AP to another. But now this has created a problem where in some of the meeting rooms, the signal strength of the closest AP is low, which causes drops, higher latency, and slow performance. This is like a catch-22!! Any thoughts on this?

Hey y'all!! My name is Doug and I am a partner with Big Fish Technology in Georgia. We work in the area of small to mid sized business and have a number of Meraki installations under management. Very exited about this community and am hoping to learn a bit more and share my experience with the community! When not working at Big Fish, I enjoy spending time with my family and good friends, working on DIY projects around the house, and spending time outdoors. ~Doug
