Slow Wifi Speeds - Hitron CODA-4582

[Ngcredible]

Hi, can somebody please tell me if my speeds look ok? 

It has been really slow on wifi lately with about 6 devices connected. I also have 500u and i'm only getting  50 mbps from wifi on my laptop.

@Ngcredible you have a cable problem of some type.  The downstream DOCSIS 3.0 channels (1 to 32) are low, but survivable.  The upstream DOCSIS 3.0 channels are above the failure point, which means that they're above the  maximum transmit power levels.  I'm surprised that the modem hasn't shut down at least three out of the four upstream channels given the power levels that are in the table.  

Call tech support and ask the tech to run a signal check on the modem.  That signal check should fail automatically given the upstream power levels.  That should be followed by a conversation to get a tech out to your home to determine what the problem is.  Most likely its an issue with the external cable and its connectors. 

The high power levels on the upstream side will affect the performance on the downstream side given how the modem operates.  

Beyond that there is also the possibility that you're sharing channels with your neighbour which can cause slower data rates, but, my bet for now is that the cable issue is causing the majority of the problem.

Thank you sir. I'll get a tech to check it out. Appreciate it.

@Datalinkso I contacted the tech through support and they asked me to run the speed test through their Rogers WiFi App which should the to modem speed of ~700, but the to device was only 55 mbps for 500u. I told them about the upstream and downstream as you mentioned above but they said there is nothing wrong with my speed.

They tried to reboot the signal but it's still slow. How frustrating because I specifically mentioned the upstream and downstream issues.

@Ngcredible what wifi channel are you using that you're running into slow data rates?  I'm wondering whether its a 2.4 or 5 Ghz channel.  

Can you download Winfi Lite from:  https://www.helge-keck.com/

Thats a freebie windows wifi analysis program, probably the best freebie program around these days.  Load that onto a wifi desktop or laptop, start the program and on the second row, near the right hand side, is a wrench icon, for the tools display on the bottom of the display.  Select that wrench icon to display the lower panel and select Spectrum, from that panel to display the graphic display of the text data.  That display should tell you how many other networks you're competing with and their power levels as well, so, in a glance, you will hopefully get a better idea of the other nearby networks that are operating.  

At the same time, sort the upper text data by RSSI.  Select the column title to sort the column up or down, in this case you want to sort the data in a downwards sort, highest at the top, lowest at the bottom.  The RSSI, or received power level is a negative scale, with 0 at the top and descending downwards to -90 dBmW.  You should see your network at the top and everyone else below your network.  

Keep in mind that there are two wifi bands, so, you can show just the 2.4 Ghz, or 5 Ghz, or both, by selecting 2.4 Ghz, or 5 Ghz or All at the top of the program.  I'd look at both bands individually, so that you know where both of your networks are ranked in relation to the nearby networks.  

If you have this loaded on a laptop, do a wifi survey around your home, stopping in places where you would normally use the laptop.  Take note of the different power levels for your networks and the competition.  

Hopefully, by looking at the data, the problem with slow data rates might be understood if this is an issue due to competing networks.  

I've asked one of the moderators to have a look at your original post as well.  Hopefully one of them can provide an explanation for the high upstream power levels.  There might be a reasonable explanation if Rogers has enabled the Docsis power level extensions, but, if so, this is the first that I've seen any indication of it.

Start with a factory reset on the C60. Then set just the required passwords and SSIDs. Set the SSID separate for 2.4 and 5Ghz. Then you can pick which radio you connect to via WIFI.If your performance is still poor, you need to boot a linux OS. That will be required to eliminate problems with Windows.
