Premier Internet SLOW!!!
A couple of weeks ago we had Cox Premier Internet service installed. We are supposed to be getting download speeds of 100Mbps. The wireless modem we are using was furnished by and installed by Cox. We have noticed no discernable difference in speed between the Cox service and the U-Verse service (6Mbps) that we had before. I have tested the speed several times over the last few days, and the download speed has ranged from a low of 4 Mpbs to a high of 12.56 Mpbs (wnich I took a few hours ago). That's not even close. Something is wrong. I have noticed that on the "My Services" page that the equipment listed for my internet service is incorrect. The Modem listed in #DSA392N, and I can't change it. The wireless modem that was supplied by Cox is a Cisco Model # DPQ3925 and a DOCSIS 3.0 type. Maybe the incorrect designation for the modem is part of the problem. I don't know, but this needs to get fixed.

I looked at the connection from our end and everything appears to be in order. Can you try testing a wired connection using a device with a gigabit Ethernet port and see what results you get?

I'll give it a try when I get a chance, but where the wireless router is located it will never have a wired connection. And why is the equipment listed on the My Services page incorrect, and unable to be changed?

The idea being trying this would be to see if it's just the wifi or the Internet connection is having the problems. Depending on the results we can go from there. As for the equipment listing that is actually the correct listing for your modem. What you're seeing there is the difference between the internal and external model number.

Chris, I work from a laptop that is always docked about 20 feet from the wireless router. Just to give you a perspective. I undocked and connected an ethernet cable from the laptop to the router. This put me about 3 feet from the router. I then ran 3 speed tests wired and wireless:
1. Wired: Download 109.69 Mpbs / Upload 11.95 Mpbs
2. Wireless 3 ft. from router: Download 32.06 / Upload 11.97
3. Wireless back on docking station: Download 28.88 / Upload 11.90
The speed drops considerably when in wireless mode, but I find it curious that the upload speed is consistent at what is spec'd. So, why does the speed drop in wireless mode regardless of the distance from the router?

This at least isolates the issue to being a wifi problem. Do you happen to know what kind of wireless adapter your laptop has? For example, wireless-G which is common for older laptops has a maximum throughput of about 32Mbps or so. To get the full Premier speeds on wireless you'll likely need a dual-band wireless-N adapter at minimum.

HI Chris,
Was out of town this weekend. My computer is a Dell Precision M4600, about 3 years old. The wireless adapter's model is a Dell DW1501 Wireless-N WLAN Half-Mini Card. It is a type 802.11n. The card has a utility where I can monitor the speed (have never opened the utility until a few minutes ago). The speed changes constantly, but has shown a high of 52 Mpbs, which I have never gotten with a speed test. We have other wireless devices as well: a Sony laptop, a desktop with an USB wireless adapter, which I just bought, an ASUS tablet, and a sling box. I will run the speed test on the other devices and see what results I get.

Your never going to get 100Mbps on wireless with just Wifi N. Real life is like 40-50Mbps, so there is room for improvement, but if you want 100Mbps+ you will either need a AC gateway, a cox modem and separate router, or go wired. Also, it might be a good idea to make the dock wired, so you can be wireless when undocked, and wired when docked.

Having the same issue since yesterday. Unplugged modem for a few minutes and ever since things have been very slow. Text is cube but graphics or video is super slow. Very disappointing.

The 1501 from what I can tell looks like a single band 2.4Ghz N adapter. With that in mind 52Mbps sounds pretty close to the max speeds you can achieve with that. It might be possible to upgrade/replace the internal wifi adapter with a faster model but that is something that you would have to address with a qualified PC technician.

From here the modem seems to be functioning as it should although I am seeing wifi interference events being logged. Can you try testing a wired connection to see if that works as it should?

Chris,
I've already tried the wired connection and it works properly - check a few posts ago. Last night I tested a few other wireless devices. My Asus tablet was able to get a speed of 39 Mpbs - don't know what it is capable of. The desktop with the wireless adapter is capable of speeds of up to 300 Mpbs, but the speed test yielded only 59 Mpbs. I guess some drop-off is expected with a wireless connection, and the speed is dependent on the capability of the wireless device, but having a device that is capable of 300 Mpbs getting only 59, is disappointing to say the least. What things could cause interference? All the devices typically report a good or excellent signal.

The problem aren't the adapters, the weakest link is the wireless portion of the gateway itself. I highly doubt you will get 100Mbps from ANY adapter connected to that gateway. It has a 802.11n, Single Band 2.4 GHz 2x2 Wireless Access Point built in. Typical Wifi N is 1x1 and has a speed around 30-40Mbps. If you have a adapter with a 2x2 antenna, you might get as much as 60-80Mbps, but thats right next to it, base case scenario. I think if your looking to get 100Mbps via wireless, you need to upgrade your equipment. See the link I included earlier for more info.

By Gateway are you referring to the wireless modem/router that Cox supplied with the installation?

Yes. That gateway can provide a 100Mbps WIRED connection, but I doubt it will ever provide a WIRELESS connection that fast. See page 2 of it's data sheet.
802.11n, Single Band 2.4 GHz 2x2 Wireless Access Point (WAP) with four Service Set Identifiers (SSIDs) or optional Dual-Band non-concurrent radio
That means two antenna, each one capable of 35-40Mbps or so. If your adapter has two antennas, then it can probably connect around 70-80Mbps, but if it only has one, you will likly get the 35-40Mbps. Thats the differences your probably seeing in the different devices. However 80Mbps < 100Mbps and 80Mbps is best case scenario. For ever little bit of interference and distant you add, you will see that drop a bit.

Your best bet for getting faster wifi speeds is to purchase your own wifi router (a dual band router with wireless AC would work best) and then have Cox exchange your DPQ3925 universal gateway for the DPQ 3212 eMTA. You then connect the eMTA the same way as the universal but connect the single ethernet port to your new router. The eMTA is provided free with your phone service and doubles as your cable modem while the universal gateway has a $6.99/mo equipment charge so you'll save money in that regard as well.
