Hi, i can't connect to my D-link dsl 2640u router by using a dynamic ip even if i use static ip and when i hardly can connect ,the router ask me to update the software , but when i load the software image the browser says it take a long time just after a short time so is there a third-party application that can flash the memory of router or fix this problem ? thanks...

A short, practical checklist to recover a DSL‑2640U and get a firmware image installed safely — tied to the tips already raised by and .

  • Connect a PC directly to a LAN port with an Ethernet cable (no Wi‑Fi, no proxy). Set the PC to a static IP in the router’s subnet (for example 192.168.1.2 / 255.255.255.0), then open and log in (default username/password: admin / admin). (manuals.plus)

  • Use only the official firmware for your exact hardware revision. Download the package from D‑Link, unzip it on your PC, and back up any router configuration before upgrading. Perform the upload from the router’s web UI (Tools / Maintenance → Update Firmware) over the wired link; D‑Link explicitly warns not to use wireless and notes the upgrade process can reset settings. (dlink.com)

  • If the browser immediately reports a timeout when you click Upload, common causes are a corrupted/incorrect file, a firmware bundle that needs extraction, a mismatched hardware revision, or a browser/PC firewall interrupting the transfer. Re-download the exact file for the H/W version printed on the router sticker, try a different browser, temporarily disable local firewall/antivirus, and use a different LAN cable/port before attempting again. (dlink.com)

  • If the web interface will not accept firmware at all, the model supports a TFTP recovery method (set a fixed IP, run a local TFTP server with the factory image in its root, hold Reset while powering on to trigger a download — LED activity shows transfer). This is a lower‑level recovery but carries risk; only use it if you have the correct factory image and are comfortable with the procedure. If unsure or the device remains unresponsive, contact D‑Link support or replace the unit. (aparcar.org)

Notes: check the H/W revision on the router sticker before any flash, and never interrupt power during an upgrade — those two rules prevent most bricks.

So you basically cannot connect to the router and access the internet? Can you download new fireware for your router and installed it?

Ok, but the problem that i can't connect to the router to install the new firmware that i download from net , i tried to install a third party program to install the new firmware to the router but i couldn't find the proper program to the router... so is there any solutions ...

okay, check the instructions on how to install that firmware, perhaps you may need to download an aditional file to merge with the firmware in order to install it to your router, can you tell me what firmware is? because when i wanted to install the DD-WRT firmware on a US Robotics i had to download an additional file and merge it, take a look from where you downloaded.
