Well, Chuck… nothing you have in “quotes” needs to “be” “in” “quotes”. Secondly get a WiFi scanner. check the signal strength. check your speeds. Check the RSSI and the SNR. The closer the RSSI and signal strength are to 0 the better (they are negative values). If you have lower speeds than you’re expecting then you know you have a combination of poor signal and interference. You could have signal overlay. there is no 11MHz or 56MHz in a signal. There’s 11mbps and 56mbps. Like I said, you’re looking at interference. If you have more than 10 devices connecting to an off-the-shelf WiFi device you’re SOL. They’re not designed to handle more than 5 or 6 devices at once. I have sold and installed higher end devices but they require doing a site survey - those cost $1500-$2500. If you want to hire my employer (based in Burnsville) I can give you a name to contact off list. We do good work, in fact you’ll end up working directly with me in the field since I’m the WiFi surveyor at the firm. But as Wayne has said concrete and metal backings are not good for 802.11 signal, or any radio signal at all. You really might be looking at a solution of well over $10,000 - be careful of what you ask for when you want to fix things. Check on your subscriber link to make sure that your service provider is actually feeding you something more than 10Mbps. CenturyLink is VERY WELL KNOWN for overstating their service. I pulled their internet after 18 hours in 2010 because they were well below advertised and they spent months before refunding me any money. — Ryan > On Oct 21, 2016, at 3:31 PM, Chuck Cole <cncole at earthlink.net> wrote: > > Need wifi setup or management parameter help.. > > Some blind folk at Cherrywood Pointe (senior living) in Savage have tech support from MN Services for the Blind for Dragon (and related) screen reading software which needs internet to function properly. Cherrywood is an Ebenezer managed facility with about 70 "independent living" residents who are cabalbe and typically affluent (rent is quite high). Wifi is included in rent. The wifi connection is erratic, and at such low speed that the software doesn't work. I'm trying to help identify the problems so thet can be fixed. "Bandaids" used before have not worked. > > What is a typical building setup? My info is only approximate now. Centurylink has a "big" fiber-optic feed to the equipment room. Cherrywood/Ebenezer equipment in the "communications room" converts to wire distribution. There is a "building router" that has multiple "CAT5" feeds that support offices and 3 pairs of access points that distribute wifi in the facility . > > All I need to know is basic bandwidth and connection info: I do not need to know anything private, and do not seek any actual admin access. > > What is a likely building router make and model? > What is a likely wifi access point make and model? > > Are there typical bandwidth or speed restrictions affecting residents and guests? > The connection speed of the 802.11g/n links is usually only 11MHz, and only once in a while 54MHz. > The internet speed is usually only about 1.5 mb/sec, and occasionally 3 mb/sec or so. > > Those numbers seem far below a typical "wifi hotspot" connection.
