Hello, @forumuser201.
Thank you for posting your query in the Community. Such low speed on WiFi indicates some severe interference. Are you experiencing this issue since the beginning?
When you say four active devices, do you mean all the devices are actively using the Internet while you check the speed?
We need to try isolating the issue. Maybe you can remove Google WiFi from the network, turn off all the devices except one and test the speed. Once confirmed the speed is good then you can add Google WiFi and other devices to the network.
Cheers,
RogersMoin
@forumuser201Can you install a Wi-Fi analyzer on a smart phone to verify that you don't have multiple access points (with a strong signal) using the same channel and verify that you have good Wi-Fi coverage in your home? I use Apple's "AirPort Utility" on my iPhone and enabled the "Wi-Fi Scanner" option in settings. Also try disconnecting your test device from Wi-Fi and reconnecting, just to make sure that you are connected to an access point with the strongest signal... and then re-run the speed test. It's possible that your wireless device might be connected to a more distant node in your mesh (and has a lower attainable speed as a result) but still has a strong enough signal that it remains connected.

Also I am only getting speeds of 200-300mbps from modem using ethernet. I called and a Roger's tech did something and had me check a d the speeds were 250mbps wifi and 550mbps ethernet. The next day the speed drops back to 200 and 20+wifi. Field tech came to the house and replaced the cable coupling on the street. The tech worked on the modem and rebooted it and the speeds were back up to 500+ and 250+ wifi. The next day the speeds dropped back down to 200/20. What should my speeds me at the modem and wifi in my house?
If you have a 500Mbps service, you should be seeing those speeds consistently when you perform a speed test with a wired Ethernet connection. I would also perform speed tests using multiple testing services. Some popular ones are:

If you are getting poor speed test results and very poor/jerky/inconsistent performance when browsing web sites, the most likely culprit is a poor connection from your XB6 modem/gateway to the Rogers network. You can check the stats by logging into the modem, then going to Gateway > Connection > Rogers Network. Scroll to the bottom to "CM Error Codewords" section. Scroll across and look at the counters; you should see very few Uncorrectable Codewords. Also, check Troubleshooting > Logs > Event logs. You shouldn't see anything other than DHCPv6 missing option errors. Look for errors pertaining to the connection with the CMTS, timeouts and ranging errors. If your modem is logging a ton of errors, call Rogers tech support.
As for your slow wireless speed tests, "only" getting 250Mbps is not ideal but also not unusual either; only getting 20-40Mbps is definitely not good at all. Before performing a test, disconnect your computer from Wi-Fi, then reconnect. For maximum speeds, you should be connecting on a 5 GHz channel and be fairly close to your modem. Your speed can be limited by several factors, including the type of wireless network card that you have in your computer, the number of devices that you have connected and using Wi-Fi in your home and the quality of their connections, and whether or not there is anything in your vicinity that could be causing interference with your wireless network.
On your set-top boxes, if you go into Settings > Device Settings > Network , it should say that "Your WiFi signal strength is good" or "Your WiFi signal strength is excellent". If you have a weak connection, you'll need to figure out out why and correct it.
Also, how are you connecting to Wi-Fi? Directly to the XB6? You can further optimize 5GHz Wi-Fi by configuring the XB6 to use channels in the 149-165 range; they transmit at higher power levels. The Technicolor XB6 is also certified to transmit at higher power levels than the Arris XB6.
Hey @jakika5!
Welcome to the community!
Seeing a much lower speed than you're expecting should certainly come as a shock. We can assist in identifying why you're seeing the speeds you are with a wired connection for sure. Over WiFi though speeds will be dependent on a variety of factors. From the capabilities of the devices connected on your network, to which network frequency you're connecting to, which channel you're connecting on, it's power availability levels of interference, attenuation, etc.
To improve your overall wireless connection, using your 5G network on channels 149 or higher would be recommended as well as ensuring that only wireless AC capable devices are connected.
On the wired connection I would recommend connecting two wired devices (or one wired, and one of 5G) and running a speed test on both devices at the same time. Once done combine to numbers, if the total is higher than what you're seeing on a singular device than the service is providing more than a single device is able to pull. This can be for a lot of different reasons related to software or hardware.
For starters I'd recommend the speed test as mentioned as well as disabling IPv6 in your modem's settings to see if there is improvement, be it wired or WiFi.
Let us know how it goes.
I'm not sure if we have a copy/paste issue but the modem's uptime is less than 24 hours and it looks like some channels have a HUGE number of uncorrectable codewords.
Okay... but when I look at the "CM Error Codewords" section, I only see columns 1-26 so part of that table is missing. Looking at your uncorrectable codewords, you have more than 14 million on one channel and more than 8 million on another. That's not good.
By comparison, my modem has been up for more than 15 days. Most channels have 0, a few have hundreds, a few have thousands of uncorrectables. I also checked Troubleshooting > Logs and I don't have any errors in my Event Log.
Search the Internet for "DOCSIS Codeword Errors" for a better explanation than what I can type up with the Forums in their current state. Codewords are basically the data that get sent over a DOCSIS channel. The data encoding allows for some errors to be corrected; relatively high corrected errors are indicative of less-than-ideal conditions but does not affect network quality from your perspective. Uncorrectable codewords equates to packet loss.
You can look at Wi-Fi performance once your Internet connection is solid. Right now, I would expect to see degraded throughput when testing with both wired and wireless connections.
@akika5, first off, apologies for the long post. No doubt the forum software will remove all carriage returns from this post, resulting in one long unruly post. Grrrrr…… Your modem is running SC-QAM channels and two OFDM downstream channels. The channels with the high uncorrected number of codewords appear to be the two OFDM channels. That does make sense as an OFDM channel runs thousands of low power sub carriers throughout its channel spectrum. Compared to what we’ve seen in the past, the presence of a large number of uncorrected codewords on an OFDM channel might not be a problem issue. There’s no indication of the OFDM channel width so it’s not possible to know if those channels are 192 Mhz wide at their maximum or if their reduced from that maximum, which would reduce the number of sub-carriers from 4096 for a 192 Mhz wide channel down to an appropriate sub-carrier count for a smaller channel. Note that its unusual at this point to see two OFDM channels running. Your post is probably the first post with two OFDM channels in operation. That does bring up the question of whether or not there are any issues with your modem running two OFDM channels. At this point in time, it’s just a question that I would normally ask.
Fwiw, if you look at the signal levels, there is an upward slope from 350 Mhz, upward. The one OFDM channel starting at 350 Mhz shows -6.2 dBmV, which isn’t great. At the same time, the signal to noise ratios, across the board, are at the bottom of the typical range for Roger’s modems which is usually 36 to 40 dB. So you have a combination of low signal levels and low signal to noise ratios. How much of an effect that will have on this particular modem model is a good question, but, it doesn’t help the situation.
Can you have a look at the bottom of the modem and let us know which modem you have? It will either be the Arris TF-3482ER or the Technicolor CGM-4140. The Arris modem is an Intel Puma 7 chipset modem while the Technicolor modem is a Broadcom BCM-3390 chipset modem. They are totally different from each other.
Can you also have a look at the back of the modem, specifically at the connected ports. Do those ports have LEDs which would indicate the link rate? If so, what color are they? Looking at your LAN “settings” as you indicated, one is at 1 Gb/s and one is at 100 Mb/s. Those numbers on a modem or router aren’t usually a setting, they normally reflect the connection rate with the connected device. That depends on the connecting cable, the connected device port and whether or not the connecting cable is connecting to both ports properly. Its possible for a gigabit port on a desktop or laptop to be set for 100 Mb/s, so if there is any question of the data rate to an Ethernet connected device, you may have to drill down into the port settings and reset the port rate if necessary. On a windows desktop or laptop which is connected via Ethernet, if you right click on the Network connection icon in the taskbar, select “Open Network & Internet Settings”. Select Properties and have a look at the Link Speed (Receive/Transmit). That should show 1000/1000 Mb/s for an Ethernet device these days. If that only shows 100/100 Mb/s then there is an issue with a port or connecting cable, or a cable connection at either port. Note that there are computer users who have “Fast Ethernet “ cables in their home. Those cables only support 100 Mb/s, so, at one point in time there were “fast”, these days, it actually slow. That link rate can help diagnose problems connecting to a modem, router or switch for example. If you do the same for a wifi connection, it will show the link rate with the modem or router. That’s not the data rate, it’s the raw connection rate as shown in the following table:
https://www.wlanpros.com/mcs-index-charts/
That connect rate can also be used to troubleshoot wifi issues.
For now, the task of the day should be to get the Ethernet performance up to where it should be. The wifi rates should increase on their own when the wired issues are resolved.
You can’t compare your neighbours wifi performance to yours, given differences in equipment, equipment capabilities and settings. A wifi data rate of 750 Mb/s would indicate using some device beyond a normal run of the mill laptop or wifi connected desktop, especially in the presence of other users in the same channel range.
Fwiw, in terms of conduced output power:
1. the channels in the 36 to 48 range are restricted to 200 mw;
2. the channels in the 52 to 144 channel range are restricted to 250 mw;
3. The channels in the 149 to 161 channel range are restricted to 1 watt.
So, even with competition in the upper 149 to 161 channel range, the output power level can result in a faster data rate compared to running in the lower channel range without any competition. You really have to test that in your own home to determine the results however, testing both lower and upper channels, fixed in place, not running on Auto.
For now, the first task is to improve the wired rates to where they should be, which is above 900 Mb/s.
@Datalink. it's not obvious at first glance but the vendor is shown on the stats page and this is a Technicolor XB6. A bunch of things about the stats page also do not look right to me either, which why I asked if there were any copy/paste issues. Regardless, the high error counts still concern me.
Hey @Alkqn!
Welcome to the Community!
This is certainly not the ideal Ignite TV experience! I'm sorry to hear you've been having such speed related issues. Have you contacted support yet? It sounds like there may be an issue getting the wireless signal where it's needed in the home. A modem relocation can be accommodated or alternatively we have our Wall to Wall WiFi option!
If you require any assistance definitely reach out to support at your convenience. You can reach support via phone/Live Chat or Social Media, information for all can be found here.
Yeah definitely sounds like its a BAD setup was done, as it shouldnt be acting that way.
I have my TV boxes on wifi, as well as usually have 4-5 devices in the same room on the same wifi pod, and all seem to run with no issues, no slowdowns that I can see (can be running the TV, netflix on a computer, playing a game, etc all at the same time).
Tuning the channels.. again something is not right there. Again if its signal or connectivity or something happening.
My ignite boxes, i find change the channels FASTER than even the newest digital cable boxes were (vs the older ones which took a good 4+ seconds to change channels)
