The Graveyard - Products No Longer Supported => Routers / COVR => DIR-655 => Topic started by: amorbis on May 19, 2016, 10:28:04 AM

Hey everyone,
I recently picked up a new DIR-655 to connect to my existing DIR-655 so I can extend my network via an access point. Now, I've followed the access point guides everywhere, including the one laid out for this exact model on here. That means I hooked them up LAN to LAN (not WAN) and already changed the IP address of Router B to something not in the DHCP range of Router A so I can access admin controls. I've also disabled DHCP and UPnP, etc.
So here's where I'm at:
The access point, or Router B, is giving out a WiFi signal that works, although it seems slow because I'm getting a fraction of what I should be getting. Wired, or LAN, connections to Router B say they have an internet connection but it seems like it's so slow that it times out. Effectively, the LAN connection doesn't work at all, but they are able to access websites for a brief moment whenever I restart Router B for one reason or another. When I check the PC that's connected to Router B via LAN, it does say I have an IP that's within the range of Router A's DHCP, so I'd assume the DHCP assigning is working. I have no idea why LAN is basically non-existent and my WiFi is so slow/unstable.
I'm working with a DIR-655 B1 (2.10NA) as Router A and a DIR-655 C2 (3.02) as Router B, if that helps.

Make sure that the radio channels differ between each 655, i.e. 655 #1 set to manual channel 11, then set 655 #2 to manual channel 1.
Modes recommended are single mode N and WPA2/AES only, disable HT20/40Mhz Co-existence.
I recommend setting the 655 running in AP mode to same IP address pool, however set the last octet to .65 or .55. You can still access the UI from this IP address.
-
Thanks for the info. I changed the IP of the AP to be within the DHCP range of the main router and I duplicated the SSIDs but with different channels. LAN still doesn't work and wifi is really up and down. It jumps from like 25mbps to 5mpbs.
-
Temporarily disable the radio on the 1st router and test. Then disable the radio on router #2 and re-enable #1 and test. Same speed problems on either?
Swap channels between each router.
- Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner (http://forums.dlink.com/index.php?topic=48327.0) to find out. How many?
Be sure LAN cable between AP and main host router is good. Swap to test.
-
I'll play around with the different channels now, but I did test the Ethernet cable that's between routers and it works fine--i get full speed on PC when connected directly to the main router.
-
Okay, so when I disable the AP's wireless, I get consistent WiFi speeds. They're small since I'm far away but they don't plummet like they do on the APs wireless. Something about the connection, both LAN and wireless, through the AP is wonky.
-
Might try doing a factory reset, manually reload the FW file, factory reset again then setup from scratch. If this all fails, then I would presume the unit maybe faulty and needs to be replaced.
-
I did what you suggested: reset ap, flashed firmware, reset again, and then ran through the ap guide again. LAN still times out or basically doesn't work and WiFi is the same. I guess I really got a defective unit? I can't see how I've done anything incorrectly.
-
Try swapping out the Rev B with the Rev C as the main host router ans test. Id problem continues, then you'll know.
-
I just did exactly that. WiFi speeds are hit or miss on the rev C as main router so that's a problem right there, BUT LAN speeds are excellent. So how could a bad wifi antenna or something mess with LAN connections when I turn it into an AP? I guess I'm skeptical if I might still have that problem with a replacement router.
-
I'm going to go get another router right now and return with those results.
-
Ya, seems like a bad unit.
-
I got a new router and it's doing the exact same things. WiFi is up and down, not consistent and LAN through the AP doesn't work.
-
What device(s) do you have connected to the Rev C that your testing with? Mfr and model # info please.
Did you turn off the Rev B radio while testing?
How is the Rev C placed? Near any other electronic devices?
-
I've discovered that my Comcast modem provides more than enough WiFi signal and I already had a spare switch. I'm going to return this DIR-655 and deal with this alternate solution. I still have no clue why the DIR-655 access point didn't work. I thank you for your help FurryNutz.
For what it's worth: I was teseting the Rev C with a ethernet-connected PC and a wirelessly connected iPhone. I tried turning off the Rev B radio with the previous unit and still had the WiFi problem, but no I didn't check it with the new one. And lastly, the Rev C was placed in a room in the basement below the Rev B, connected to each other via an ethernet cable that I made sure was working. The Rev C was near a PC, I guess, but I doubt that would actually affect it, especially when it was upstairs and witnessing the same problem next to no other devices.
I guess I have to end this in defeat. I'm not sure I'll ever know what doesn't work.
-
Thanks for the feedback and info. Ya, seems odd. I'll connect my Rev C in AP mode and see if mine does the same thing. I do have a customer of mine that has a Rev C running in router mode with a AC class bridge connected to it and has been working great there. I haven't ran my 655's in a while so I'll check on this.
-
Would it have anything to do with a Comcast modem/router not being in bridge mode? When I was testing everything the Comcast gateway had its own routing stuff on. I can't seem to find any evidence if that would make my ap plan go wrong though. It also wouldn't explain the poor wifi when connected straight into the Comcast router/modem.
-
Does the ISP modem have wifi as well? If so then yes it could effect other wifi signals.
I connected my Rev C yesterday in the far end of the house. I did a quick test on my MacBook Pro from the other end of the house, I didn't see my 100 spec speed however saw about 30Mb on the down and was steady. Internet seemed normal.
-
Yes, the ISP modem has its own wifi signal. I've been reading about it, and Im wondering if bridge mode on it is a solution. Can the modem having its own DHCP cause issues with the access point?
-
Yes possible.
It's recommended to bridge ISP modems if possible and use the DIR router as the main host router. The connect up any 2ndary wired APs.
-
I still have the new router. I might give it a shot, mostly because I Want some resolution to this problem! So if I put my ISP gateway into bridge mode do I still leave it connected to the rev b in the WAN port?
-
Yes...test the Rev B first as the main host router. Once thats done I would turn off the radio on the Rev B router and then install the Rev C as wired AP. Be sure to connect Rev B LAN to Rev C LAN. turn OFF ALL features like filters, SPI, uPnP and DHCP, I set mine for 192.168.0.65 and set single mode N, WPA2/AES manual channel 11. Try other channels. It should work. Test with different wireless devices to be sure if you can.
-
Alright, that sounds like a plan. I'll give this a shot in a bit and let you know how it goes. Again, thanks so much. Even though nothing has worked yet, I feel like I've learned a lot.
-
Whats the Mfr and Model# of the ISP modem?
-
It's an Arris TG862G, the Comcast version.
-
I followed your instructions and the wired connection tests right but websites aren't loading--now I'm more confused. WiFi is the same: it looks good then plummets more than I thought wifi should, like by 10 mbps. And this is with rev b wifi off. I'm going to try different channels I guess. I don't know what's up with the LAN speed testing correctly but not accessing websites though.
-
Try the Rev B in AP mode as well and see. Ya, this is odd for sure.
-
I tried a few scenarios. Nothing was making the DNS errors go away via LAN and the WiFi remained unstable. I'm sticking with Plan B on this one and returning the router.
