Clients gets wired fiber connection of 500 megabits but 10 meg for wifi on phone

Speedtest.net recorded a ridiculously good connection for a residential ATT address.  The client wishes to have a somewhat comparable speed via wifi.  However, the table gets 50 or 60 megabits and the iphone gets 10 megabits.  Both G and N are disappointing speeds.  The router is mounted to a wall.  I will make the visit on-site wednesday to view this on-site but I'm not sure what if any guarantees I can fix the situation with the existing hardware.  Any suggestions?

In the real world, those numbers are not too bad. The 300Mbit rating is the theoretical maximum burst rate for 802.11n, not expected throughput.

In the real world, if you take care to ensure no other WIFI devices or other electrical noise is around, then have a high end laptop about a metre from the base, and have just one device in use, you MIGHT get 100Mbit or so.

Your router is easily capable of delivering over 100Mbps throughput over Wifi.

Have you tried both the 2.4 and 5GHz bands to see whether you have a co-channel interference issue? Such a poor service is usually attributed to other devices using the same channel. It could be a config issue though.

He's tried tried both bands.  I could set it to be channel specific using Netspot but I doubt that will be the fix.  We have a ubiquity Unify AP coming in the mail for tomorrow's on-site meetup

The bottle-net is normally at interference among all wireless devices.

What is the model of your iPhone?

How many wireless devices are in use?

Which channel are set at the router?

OK, I worked on-site yesterday.  Sorry, I missed the last message but here's what came out of the visit.  He had two services:

Cox 500 meg

Cox 500 meg service was run off his own modem/router purchase of a Netgear AC19xx WiFi Cable Modem Router.  Model: C7000.   WiFi speeds on phone or laptop were between 100 and 200 megabits

ATT Fiber

The client replaced Cox a month ago with ATT Fiber because he thought he get twice the speed.  A hardwired connection is 500 megabits and varies between time of day.  His ATT leased modem/router/wifi gets 17 megabits.  

Netgear Router

He purchased the Netgear router mentioned in the original question/post to overcome the issues with ATT crap hardware.   We set the ATT router to bridge mode or passthru and enabled the router to handle all the devices and WiFi.  The speeds limped along at 37 megabits.

Ubiquity Unifi AP

I removed the Netgear aftermarket purchase, added the Netgear, relocated the AP to the central area of the house, and used NetSpot to find some free channel in the suburban track home neighborhood.  All this did nothing to improve the wifi speeds.


Revisit Netgear Cable Modem

I dumbed the Netgear cable modem he used when he had Cox to an Access Point.  Now he's seeing double the speeds on the WiFi...  80 megabits

Bottom Line

I told him he had a good thing going with Cox and suggested he go back.   I have no idea why he can't produce the 100 to 200 megabits WiFi speeds he said he had with Cox.

What is the brand and model of ATT modem / router? The problem is from the wired connection between the ATT modem and the Net gear router.

I'd do a scan with Acryllic Wifi Scanner on both bands and post the results here. It definitely sounds like co-channel interference as I said earlier.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Craig - How do you explain that significant jump in wifi speeds with the Netgear WiFi cable modem router?

Jackie - It's a Arris, similar to the one mentioned in Reddit

ATT modem/router can still produce crazy speeds when wired as seen in the attachment.

Power output maybe. There's lots of things that can have an effect.

When you're testing, how far from the router are you?

Close, far... mounted high, side... whatever.  It doesn't seem to matter.  It just works when I plug in the cable/modem/AP from Netgear

Are you using WPA2/AES to secure the Wifi?  If you're using TKIP you won't be able to get the faster speeds.

We returned the Ubiquity Unifi AP.  Attached is the latest speeds from the dumbed down cable modem router turned AP.  Crazy how none of the other hot spots struggle to get even remotely close to this wireless speed.

Anyone got a favorite WiFi router that will do a solid maintaining high speeds?
