Hello there,
I hope you might be able to help me with this. I recently bought DIR-605L N300 Cloud Router and I like it quite a lot. However I'm having a small issue.
When connected via LAN, my internet speed would be around 40 Mbp/s. When I am connected via WiFi, my speed is 28 Mbp/s no matter how far/close I am to the router. Second floor - 28 Mbp/s, First floor - 28 Mbp/s, 2 feet away from the router - 28 Mbp/s. 10 feet away - same 28 mbps.
I live in a sort of a suburb neighborhood and there's not more than 1-2 other networks visible around me so noise is not an issue.
I've configured the router to use a wide 40 Mhz channels, and have ensured the channel picked is as far away as possible from the other networks' channels. 20/40 Hz co-exist disabled. WPA2 AES PSK encryption. Wireless mode is Wireless Router. 100% Transmission speed. Enhanced Wireless option turned on. Wireless mode "n" only.
The max connection speed as detected by my laptop is 300 mbs (checking from the WiFi connection in Windows).
Firmware is up to date.
Do you have any clue as to why a 300 mbps router can't utilize at least 90% of my internet's bandwidth?
Any help would be appreciated!
Thanks!

Any status on this? ???

Hello,
Actually yes. After waiting for quite some time I got a response back from Support who suggest I update the firmware. They gave me a set of steps to follow. The problem is now gone and I have 98% of my LAN speed up in the WIFI signal. Out of 50, I get 48 Mbps on the second floor.
Notes:
- I had initially followed the Firmware Update process directly from the Router's admin page. For some reason, the firmware I got from there was not the same as the one I was directed to by support. The support instructions directed me to a slightly different page where I got a newer version of the Firmware. After installing it though LAN on the router it got up to full speed. Funny how 2 official channels of the same company (2 firmware update directories etc.) can yield totally different results for the same product.
- After installing the new Firmware I imported my router settings I have previously saved. It reduced the router's speed back to the 28 Mbps it was stuck on before. This was not caused by my personal settings, because with the old firmware it wouldn't work even after a master Reset, but I suppose it carries some of the bugs with it. So do not import settings - just replicate them and it will work.
Hope this helps.

Glad you got it working.

Hello,
Need to revive this.
After upgrading my internet connection I was able to better identify the problem I am facing. WiFi speed is 3 times lower than what I have available unless I restart the router. After restart I make use of the majority of the bandwidth, but after an hour or so it drops back down and needs a restart.
So what causes the speed drop and how can it be avoided? Firmware obviously doesn't fix that sadly :(
-
Try setting 20Mhz channel width and test.
What ISP speed do you have now?
Any other Wifi neighbors near by? How many?
-
Hi there,
I've done tests with both 20 and 40 mhz channels. Nothing changes. Speed is high the first 1 hour and then router needs a restart or it stays low.
There's 4 networks besides mine near me. All except 1 have -80/-90 RSSI. The remaining one has high RSSI but it's on the channel furthest away from me.
Thanks,
T.

How many wireless and wired devices do you have connected at once? 2 (laptop and smartphone)
-
Can you confirm the FW version # and your region your located in?
One think you might try, remove the router from it's wall location and then place on a desktop or wooden table. These get hot sometimes and I'm wondering if there maybe a heat problem. Do you have a laptop cooler handy by chance?
-
Hello,
I will confirm the Verison a bit later after I get home.
To the heat suggestion - that was something that the IT from the company I work in also suggested. I took the top cover of the router off and stuck a copper heat sink on to the CPU with some thermal paste. I left it on throughout the whole night last night, with the cover off. When I woke up I had 15 Mbps download speed on the speedtest. After a reboot it went up to 65 Mbps again. So I suppose we can eliminate that. The only thing I haven't tried yet is putting heat sin on the other chip (the smallest one of the three), but I'm told that is not relevant. Still I can try.
I read on some forum via google search that this may have to do with bad RAM management and that OpenWRT firmware might solve it for most people, but it seems this router model isn't supported by OpenWRT.
Best,
Toma

What region are you located?
-
Eastern Europe, Bulgaria.
-
Let us know the version you have loaded.
I'd like to have you do a factory reset, manual reload of current or newer FW, factory reset then set up from scratch and test again.
If it still happens, possible that the unit is faulty and needs to be replaced.
-
Will do and revert back with the results in a few days.
One question though - Sticker on the back of the router says Revision B2. Chipset model also matches Wiki for Rev B2. However it says Rev-A1 on the actual board, close to where the chipset is. I guess we stick to Rev B2 right?
Regards,
T.

Yes, let us know the version your currently using.
I recommend starting a support ticket with your regional D-Link support office:
http://www.dlink.com/bg/bg/support/contact?product=DIR-605L&description=Bad+wireless+after+1+hour+of+operation (http://www.dlink.com/bg/bg/support/contact?product=DIR-605L&description=Bad+wireless+after+1+hour+of+operation)
Be aware that you cracked the case on the router thus probably voiding the warranty. So not sure if you can get any RMA help on this. Unless you put it back to to original design. ::)
-
Hi there,
Product Page : DIR-605L / Hardware Version : B2 / Firmware Version : 2.06UI
I will raise that with support.
The case is not broken or something - it just pops on and off. There are however screwdriver marks (while popping it open) so I guess that still does count as voiding the warranty. Anyhow I will redo the firmware thing soon and see what happens next.
BR,
T.

Might try v2.08 as I see it's available as well. Not sure if it will help. Worth trying.
Good Luck.

Hello,
Okey so despite the different support pages showing different release latest firmwares, and everywhere a different release date is shown, I installed 2.08 b02. I did as suggested. Factory reset. Install new firmware (cabled). Factory reset. Setup. Testing - same thing. 50-60% drop in speed both in WiFi and LAN. Also, both the chips on the board have heatsinks on them now. I give up.
I guess that is normal for a 15 EUR router. It will keep the average Joe connected to the internet but apparently it just can't sustain anything above 25 Mbps, let alone 300 as advertised.
-
I would give your regional D-Link support office a call and ask for an RMA. I presume this router maybe faulty is all.
300Mb is a connection rate between the router and wireless devices that support 300Mb connection rates, it's not a actual data transfer rate.
-
Hello,
Local Dlink support agreed what I am reporting is impossible, and told me to avail of the warranty. I did, and I just spoke with the tech who was testing my router. He claims the router has been working since yesterday and he's getting 80 Mbps on LAN, and 30-40 Mbps on WiFi. Claims everything works fine and there's no problem with the router.
I guess that even though I am paying for fast internet, and fast 300 Mbps external dual antenna wifi adapter, I'm still not gonna be getting anything more than 20 Mbps wifi and 40 on lan. Seems there's no way to convince them it doesn't do its job.
@ FurryNutz - I am much obliged for your assistance in this matter!
Best,
T.

You might try and get someone on site to review your router settings and situation.
Be aware that 300Mb is a connection rate between the router and wireless connected devices. Not a actual throughput speed.
I recommend that maybe testing a new router out will be of some help as well.
Good Luck.

Hi there,
I've tried with Stock Settings, and with custom settings. I've tried 20 mhz, and 40 mhz channels, Ehance mode enabled/disabled, hidden SSID, Unsecure/secure, firewall with/without, everything. Behavior is all the same. Here are some screenshots prooving that the router is generally capable:

Speed tests done at different times of the day, but still just after the router has rebooted, show I'm getting the bigger part of my 75 Mbps downlink speed easily. Mind you, that is from the second floor of the house, while router is on the first. Yet 1-2 hours later we're back at 30 Mbps until rebooted again.
I will try getting another router just for the sake of testing, but I did encounter a post on another forum, where a user reported the exact same situation, to which Dlink responded by sending a replacement router (Rev A though). The user reported the problem with it was even worse. So I assume this is somewhat normal for this model.
-
Are you getting to spec speeds on a wired PC?
-
Yes, both via the router and directly with the cable from the street into the PC. Though LAN speeds also tend to drop in time, but remain better than WIFI is.
-
If your getting spec speeds on wired then this is all that needs to be done. Wireless can be problematic on any router and due to all the variables in wireless and wireless devices, speeds seen on wireless may not be accurate due to these variables. Especially on 2.4Ghz. Again, wireless connection rates differ from actual data through put. If your getting wired speeds to spec then you'll be fine.
-
Yes, indeed. But I didn't feel like running 20 meters of lan cable to get it upstairs, so I bought a wifi router. But yeah my options are clear now, and I know a bit more about routers than I did before.
Once again - sincere thanks for helping me with this Furry!
-
One suggestion if you need additional signal upstairs and avoid additional wires, Try installing a Power Line adapters then install a stand alone AP up stairs.
Or get a range extender...
