@CDNTechEast if your a Rogers Emplloyee, flip over to this Forum for a while;
and take a look at the over 350 pages of complaints about the CODA firmware and the LACK OF response from any Rogers Certified Network Staff
Your not the first and wont be the last to get "concerned" about Rogers services and devices
The black dot at the back of the modem signified that additional shielding had been installed over the cable's DOCSIS tuner. Two dots signified that the modem had been tested as well. Now, that's been a while back and I don't know if that policy is still in effect. I suspect that isn't the case anymore and that additional shielding is now part of the design and production. Rogers has recently received 20,000 of these modems, so, in theory, they should all have additional shielding installed.
Without that shielding, the wifi's 2.4 Ghz network would cause EMI issues with the DOCSIS tuner, so the modem's performance as a whole would suffer.
In theory the white 4582 should have better basic wifi performance. The 2.4 and 5 Ghz antenna are all at the top of the modem instead of being mounted on the motherboard, where there was the possibility of interference from parts of the motherboard. Just to note, Beam Steering for 802.11ac wifi networks is not enabled on the modem, which is unfortunate. That might not make a huge difference, but is probably enough to move the wifi adapter down to the next, and faster level, in terms of the Modulation and Coding Index level that the adapter is running at. That index can be seen here: http://mcsindex.com/
As for the wifi issues, can you direct your sister's attention to the following post:
That post includes wifi settings for the modem which will hopefully alleviate some or all of the issues. I say some or all as each home is unique in terms of the wifi interference that it sees from its neighbour, so, part of this issue is to understand what you're dealing with in terms of clear channel competition. That's the second part of the post, to determine who your competing with and determine what you can do about it, if anything.
I'll have to update that post as Metageek, the makers of inSSIDer have come out with an inSSIDer Lite version. Hopefully that will make up for the fact that they appear to have abandoned the home wifi market. That lite version should display the local 802.11ac networks from her neighbours homes. The inSSIDer version in that post only properly displays the 802.11n networks and attempts to display the 802.11ac networks. The Lite version will hopefully do that properly. Only hitch appears to be a requirement to set up a freebie account with Metageek. This version has only been out for about a week, so, I don't know if there is any way around the freebie account setup.
I wouldn't count on Tech Support to necessarily look at the specific wifi settings. The feedback that I've had from other customers in the same situation is that changing the wifi settings as suggested in that post has made a difference, so, I'd check those first and adjust them as necessary and then check out the wifi environment to see who she's competing with. Changing the 5 Ghz channel to 149 or above and setting the bandwidth to 80 Mhz should help. That channel change to 149 or above allows the modem and devices to use 1 watt for a max power output. Channels 36 to 48 are restricted to 50 or 200 milli-watts depending on when the device was approved by Industry Canada, and the middle Dynamic Frequency Selection channels 52 to 144 are restricted to 250 milli-watts. So, moving up to the top channels should result in better received power levels, better signal to noise ratios and better data rates. That is incumbent of course on the local competition from nearby modems and routers.
Thanks again DataLink.
Can you remind me again, or provide me with a link on how to access the admin/settings of this modem? It's been a while. Something tells me that I'm going to be doing a tech support visit to my sisters after work today.
@Radar2000 to access the modem's user pages, bring up a web browser and enter 192.168.0.1 or 192.168.100.1 into the address bar to access the login page. The credentials are;
password: the modem's wifi password (unless your sister has logged into the modem and changed it to something else, which can be done to separate the wifi passphrase from the modem password. )
From there you can navigate to the Wireless .... Basic Settings tab. Check the settings for both 2.4 and 5 Ghz sub-tabs as suggested in the following post:
When all of the changes have been made, reboot the modem ADMIN .... DEVICE RESET .... Reboot.
Gateway function on Hitron CODA4582
I recently got and setup the ASUS RT-AC86U wireless router. But removed it from the setup as i was not happy with how it was not fully showing the connected USB HDD contents consistently.
So I put the Rogers modem out of Gateway mode. But i had to call customer support and they did it remotely as i could not even access the admin page at the default ip address.
After reviewing further for alternatives to ASUS router that I got, I don't see much other better alternatives for the $250 price range for features that i want (longer wifi range - 2200 sq ft house, parental controls, usb ports for within home hdd data sharing, malware protection, multiple function modes (Access point, Repeater, Router).
So I want to give the ASUS router another chance. But this time, just wondering if I can continue to use the CODA like as it is now, without putting it in bridge mode by just taking the output from one of the Ethernet ports of CODE and supplying as input in the WAN port of the ASUS router and then setup the ASUS router wifi SSID to a different one ?
I recall trying this with my older unused ASUS-RTN13U router and it had not worked. I assumed it was due to issues with that router.
